To determine the height of a ride, use a simple “protractor elevation finder.”

Have one student sight through the straw

(using the proper elevation given standing on the designated area) at the top of the ride.

Another student reads the angle on the protractor. The angle read is then subtracted from 90 degrees.

To calculate the height of the ride you will also need the distance (given to the students at the designated elevation sighting locations) between the students and the ride.

1. Cut out the protractor including the dashed line section.

2. Trace the protractor part only on a piece of cardboard. (The back of a tablet works

nicely).

3. Glue or staple the cardboard to the back of the paper protractor.

4. Roll the top section around the straw and tape.

5. Punch a hole and tie a 9 inch string of heavy black thread through

the hole. On the other end tie a nut or fish sinker.

6. Follow the directions on the page titled “An Angle on Distance.”

MMOOTTIIOONN

There are two basic types of motion. Motion that is uniform and accelerated motion.

For uniform motion, forces are balanced. There are no net or resulting forces. Under these

conditions calculating the velocity is straight forward.

Velocity = =

This velocity is an average for the trip.

Whenever an unbalanced force acts on an object, an acceleration is produced.

Acceleration = = or F = ma

F= Force, m= Mass, a= Acceleration

As you can see force and acceleration are related. Acceleration is the change in velocity over a

period of time. (How fast something is going faster.)

Acceleration = =

Acceleration occures anytime there is a change in velocity. For objects moving in a curved path,

velocity is changing even through speed may be constant. Velocity is a vector and therefore must

have speed and direction. If your direction is changing, like on the Super Round Up, then there is

an acceleration toward the center of the Super Round Up. This acceleration is called centripetal

acceleration.

Centripetal Acceleration = (velocity)2 ÷ radius V

Ac = Ac = Centripetal Acceleration

V = Velocity Ac

r = radius of the circle

In the case of an object spining in a circle, the size of the velocity (speed) is calculated by

measuring the time for one complete spin and dividing this into the circumfrance of the circle.

If there is an acceleration there must be an unbalanced force producing it. The force causing the

circular motion is called centripetal force (Fc ). This force causes the object to change direction

thereby creating the acceleration in the same direction (towards the center).

As stated previously; F = ma

This is Newton’s 2nd

Law of motion and must apply to circular motion.

But note that: Fc = mac

ac = note the equation for ac

If we substitute in for (ac), we find the equation needed to calculate centripetal force.

Fc = mac becomes Fc =

This force is easy to see and understand if you swing a rubber stopper on the end of a string. You

can see your hand is producing the force which is transferred through the string to make the stopper

follow a circular path.

In the Super Round Up, the wall produces the centripetal force. This force keeps you moving in a

circular path by providing an acceleration on you toward the center. You, on the other hand, have

the impression that there is a force throwing you toward the wall. This is very similar to being in an

automobile at rest and the driver pushes the accelerator to the floor. If the car has a lot of

horsepower, you feel like you are being pushed back in the seat. In reality, the seat is accelerating

you forward. So, in the Super Round Up, the force you feel out against the wall, called centrifugal

force is a fictious force. You are reacting to the wall pushing you in!

Think of centripetal force as the action force and centrifugal force as the reaction force.

Remember, centrifugal force is considered to fictitious. It can only be observed in the acceleration

frame of reference.

These forces are also found on many other rides at Idlewild. Any ride which moves in a circular

motion or curved path will produce centripetal and centrifugal forces.

Acceleration Finder The accelerometer is a device used to measure the acceleration of any moving object. For this project you will be observing the centripetal acceleration generated by the Carousel. Accelerometer Construction Materials Needed: Clear plastic bottle with lid that is closely the

same diameter of the bottle. Glue String or fishing line Fishing bobber (1”-2”dia.) the bigger your

bottle the bigger your bobber should be. Example: If the bottle is 3½“ in diameter the bobber should be about 1”-1½” in diameter.

Strong box tape Scissors Newspapers Water

Accelerometer Construction Directions: 1) Lay out your newspaper for easy

cleanup. 2) Attach the bobber to one end of the

string and hang it inside the bottle with the bobber just barely touching the bottom of the bottle.

3) Cut the string at the top of the bottle exactly at the same height as the lid. 4) Tape the string in the center of the lid with your box tape. Make sure the string is in the

exact center of your lid.

5) Place the bobber inside the bottle and close the top. The bobber should hang inside the

bottle without touching the bottom of the bottle. Approximately ½ inch from the bottom. 6) Fill the bottle with water approximately ½ inch from the top. Place the bobber inside the

bottle again and close the top tightly and securely. 7) Turn the bottle upside down and check for leaks. If it leaks, turn it back over and let it dry

where it leaked. You will need to seal the lid with glue with the assistance of your teacher.

Average

Averages are obtained by adding the numbers in a set and dividing their sum by the total of the

elements involved.

For example, the average of 3 and 7 is 5

Calculated 3 + 7 = 10; 10 ÷ 2 (the total of elements in the set) is 5.

The average of 96, 89, 13, and 2 is (96 + 89 + 13 + 2) ÷ 4 = 50.

Percentage

The term “percentage” is derived from the Latin word per centum, meaning “per hundred,” this

term essentially represents fractions with the denominator of 100. Therefore, 35 percent (35%)

means the fraction 35/100.

To find the percentage of a number—for example, 20 percent of 40—20 must be changed to a

common fraction (20/100) or to a decimal (.20) and the figure multiplied by the whole (40); see

below

The percentage relationship of one number (5) to another (20), is calculated by dividing the first

number by the latter number then just multiplying this by 100; see below

5 ÷ 20 = .25, .25 x 100 = 25 percent or 25%

WWIILLDD

MMOOUUSSEE

Hidden among the trees, Idlewild’s Wild Mouse is a modern version of the classic Wild

Mouse roller coasters, featuring mouse-shaped cars carrying four riders each. Once the

cars are hoisted to the top of the lift hill, they must follow the sudden twists, dips, and

hills that will lead them back to the station.

The velocity at the base of the Wild Mouse first drop is represented by the formula:

V= gh (squared)

Using the method discussed in the Student Activity Guidebook “An Angle on Distance”,

find the height of the Wild Mouse at several points of the first drop. (Use the markers on

the ride and the designated sighting location to make your calculations.) The sighting

location is just after entering the entrance line to the ride. Follow the path until you pass

some rocks making up the entrance line. When the rocks end, look to your left. The tree

is located approximately 3 meters to the left marked with a red bull’s eye.



1. Height of column A from the ground:

Height of point A = distance away ( Tan )

the drop.

______________ – ______________ = ___________________

10. Velocity of the first drop:

Now that you know the height of the drop at it’s highest point and lowest point, use the

velocity formula at the beginning of the question to calculate the velocity at point B in the

Carousel (Accelerometer required) Safety Precautions: You MUST stay between the inner and outer horses AT ALL TIMES while the ride is moving. Do not walk around the ride while in motion. Failure to follow this rule could result in personal injury. It will also result in your removal from the ride and possible loss of your rider’s pass for the remainder of the day. Directions:

1. Place the accelerometer lid side down on the deck of the carousel behind an inside horse.

2. Stand beside the accelerometer and look down so that one eye is directly over the bobber. Notice the location of the bobber.

3. As the ride begins to move, notice the motion of the bobber. 4. Take note of where the bobber is in relation to the center of the accelerometer. 5. After observing the accelerometer for one ride move behind an outside horse after

the ride stops. 6. Once again place the accelerometer on the deck of the carousel.



7. Notice where the bobber is in relation to the center of the accelerometer. Continue watching the accelerometer until the carousel has nearly stopped.

8. Once the ride has come to a complete stop you may step off the platform.



Questions:

A. What happened to the bobber as the carousel began to move?

B. While riding by the inside horse, where was the bobber (in relation to the center of the accelerometer)?

C. While riding by the outside horse, where was the bobber (in relation to the center of the accelerometer)?

D. By which horse, the inner or outer, did the bobber move further away from center?

E. Based upon your observations, where is the centripetal acceleration greatest? Why?



1. Which number position on the diagram would you have the greatest speed? _______

2. Which number position on the diagram would you have the smallest speed? _______

Investigation #5 Rollo Coaster – Idlewild & SoakZone 2000 37


RROOLLLLOO CCOOAASSTTEERR

The Rollo Coaster was built by the Philadelphia Toboggan Company and opened to Idlewild’s Guests in 1938. It’s two trains carry riders up and down along a wooded hillside, only to turn around in a swooping curve and return back towards the station. The rides last approximately 70 seconds on a track that runs nearly 1400 feet. The Rollo Coaster has been named an American Coaster Enthusiasts Classic Coaster.

Please keep the following in mind while doing your calculation: Some days the Rollo Coaster operates with two coaster trains. If you are visiting on one of these days, please know that one coaster normally runs a little faster than the other. Also, rain tends to make the coasters run a little faster and the heavier or larger group of people in a coaster will cause it to run faster, while cold temperatures cause casters to run slower.

Note: You must be 48 inches tall to ride or be accompanied by an adult.) This investigation will require you to ride the Rollo Coaster. Because of this fact, one individual would have to ride the coaster between 15 and 36 times to obtain the necessary information, which we do not suggest. Therefore, it is recommended that this investigation should be done as a TEAM, in groups of 5 to 10 individuals, sharing the findings.

1. Using a stopwatch or the second hand on your watch, time how long it takes the train to

give one ride. The train travels 411.48 meters from when the train starts moving until it

stops to unload. Start timing the train as soon as it begins to move out of the station until

it stops completely at the back of the station to unload the people. Make several

measurements and find the average. All Start and stop points are marked on the ride.

Some calculations may require riding or observing from the midway. (If two trains are in

operation, be sure to clock the same train entering the station)

Potato

Patch

1. Find the average length of a Potato Patch fry.

Get a complimentary cup of “experiment size” fries at the Mineshaft Kitchen,

Potato Patch Fries stand. Go through the line and show the cashier your

worksheet for this activity.

Total Length of Fries Total Number of all Fries combined = Average Length

Note: If you find a fry shorter than 1 inch, do not count it in the total number of fries but do add it to the total length.

2. How many servings of fries would it take to follow the entire track

of the Wild Mouse (1,640 feet) if the fries were laid end to end?

Total Length of the Track Total Fry Length (Total Length of all Fries combined) = Amount of servings required
