Work in groups at the lab stations I will assign a random problem to each group

to show. You will have 5-7 mins to show the original graph, linearized graph, and along with the math model including units

I will pick one group member to present so make sure every understands what was done in the lab.

This is the HW grade for the worksheet and it’s a group grade. Everyone is responsible for knowing their groups info.

Test Review

The length of the string is…

The actual length of the string suspended in the lab was 8.809 meters.

You will now calculate your percent error as it relates to this lab.

To calculate percent error: http://www.wikihow.com/Calculate-Percentage-Error

Make sure your prediction is in meters. If it is not, use one or more of the following conversions:

1 inch = 2.54 centimeters; 1 meter = 3.28 feet

Groot & Peter Quill in An orb throwdown

Groot begins 10 meters ahead of Peter Quill as they both move in a straight linear fashion towards an orb (that possesses the Infinity Stone).

Groot moves 0.5 meters each second. Peter Quill moves at 1.0 meters each

second in the same direction. When will Peter Quill catch up to Groot?

Displacement

Motion Maps

Worksheet

Quiz Friday

What is Displacement?

How is it different than Position and Distance?

What Information does Displacement give?

Displacement

The change in position is the displacement. It can be both positive and negative like position.

Calculate how far car has travelled when it travels at a constant velocity of 5 m/s for 20 seconds

Displacement

10 meters

Now this can be calculated many different ways using velocity and time. All of you have calculated it algebraically.

How can you graphically come up with the answer?

Displacement

Graphically

20 seconds

5 m/s

The area under the curve on a velocity vs. time graph gives you the displacement

Check the units

Extra examples (board)

Area

Think of them as tiny snap shots of time Each dot represents an even increment of

time The arrow represent a velocity

Motion Maps

Consider the interpretation of the motion map below. At time t = 0, cyclist A starts moving to the right at constant velocity, at some position to the right of the origin. Cyclist B starts at the origin and travels to the right at a constant, though greater velocity. At what time does cyclist B overtake A?

Draw a motion map of a person walking at 5m/s for 10 seconds

Draw a motion map of a man walking -5 m/s for 10 seconds

Draw a motion map of a man walking 5 m/s for 5 seconds, remaining idle for 1 second, and then travelling -5 m/s for 5 seconds
