MAIN TOPIC?
The main topic of this chapter is __________, which is a change in an object’s position relative to a ___________ point.
MAIN TOPIC?
The main topic of this chapter is MOTION, which is a change in an object’s position relative to a ___________ point.
MAIN TOPIC?
The main topic of this chapter is MOTION, which is a change in an object’s position relative to a REFERENCE point.

3 formulas we will be using
MOTION
3 formulas we will be using -- speed

3 formulas we will be using -- speed -- momentum
MOTION
3 formulas we will be using -- speed -- momentum -- acceleration
SPEED IS
SPEED = distance divided by __________
SPEED IS
SPEED = distance divided by TIME
EXAMPLES OF SPEED
50 m/s 200 mi/hr 20 cm/min
INSTANTANEOUS SPEED
Instantaneous speed is speed in an ___________ of time WHILE average speed is the _____________ of your speed over a trip
INSTANTANEOUS SPEED
Instantaneous speed is speed in an INSTANT of time WHILE average speed is the _____________ of your speed over a trip
INSTANTANEOUS SPEED
Instantaneous speed is speed in an INSTANT of time WHILE average speed is the AVERAGE of your speed over a trip
INSTANTANEOUS SPEED
For example, you may have ______________ on your brakes when a dog runs in front of your car ….so slower speed at that moment……
INSTANTANEOUS SPEED
For example, you may have SLAMMED on your brakes when a dog runs in front of your car ….so slower speed at that moment……(THAT INSTANT of TIME)
INSTANTANEOUS SPEED
Another example would be if you ____________ when the stoplight turned green.
INSTANTANEOUS SPEED
Another example would be if you HIT THE GAS when the stoplight turned green.
Average SpeedRace Number
Average Speed
1 120
2 130
3 130
4 160
What is the average speed of all the races?
Average SpeedRace Number
Average Speed
1 120
2 130
3 130
4 160
What is the average speed of all the races?
120 +130+ 130+ 160 = 540
540 /4 = 135
GRAPH
Average Speed Dividing total distance by total
time calculates average speed.
SO……..If the whole trip totaled 30 miles and took 3 minutes to go the 30 miles…..then
(30 miles / 3 minutes) = 10 miles/minute

MOMENTUM
Momentum is based on _______ and _________ of an object.
MOMENTUM
Momentum is based on MASS and _________ of an object.
MOMENTUM
Momentum is based on MASS and VELOCITY of an object.
MOMENTUM
If the mass of an object is small, for the object to have a lot of momentum, it must be traveling relatively __________
MOMENTUM
If the mass of an object is small, for the object to have a lot of momentum, it must be traveling relatively FAST
MOMENTUM
If the object is traveling very slowly, for it to have a lot of momentum, its mass must be relatively __________
MOMENTUM
If the object is traveling very slowly, for it to have a lot of momentum, its mass must be relatively LARGE
Acceleration
Acceleration is when an object SPEED UP or _____________ or changes _______________
When you speed up = acceleration When you slow down = acceleration When you change direction =
acceleration
A carousel is an example of acceleration
Acceleration
Acceleration is when an object SPEED UP or SLOWS DOWN or changes _______________
When you speed up = acceleration When you slow down = acceleration When you change direction =
acceleration
A carousel is an example of acceleration
Acceleration
Acceleration is when an object SPEED UP or SLOWS DOWN or changes DIRECTION
When you speed up = acceleration When you slow down = acceleration When you change direction =

A carousel is an example of acceleration
Acceleration
Acceleration is when an object SPEED UP or SLOWS DOWN or changes DIRECTION
When you speed up = acceleration (positive)
Acceleration
Acceleration is when an object SPEED UP or SLOWS DOWN or changes DIRECTION
When you speed up = acceleration (positive)
When you slow down = acceleration (negative)
Acceleration
Acceleration is when an object SPEED UP or SLOWS DOWN or changes DIRECTION

ACCELERATION
________________ Acceleration is acceleration towards the _____________ of a curved or circular path
ACCELERATION
CENTRIPETAL Acceleration is acceleration towards the _____________ of a curved or circular path
ACCELERATION
CENTRIPETAL Acceleration is acceleration towards the CENTER of a curved or circular path
?
Speed + direction = ______________________
?
Speed + direction = VELOCITY
Speed / Velocity
Velocity is speed plus a direction.
50 mi/hr is speed of a car 50 mi/hr going North is
the velocity of a car.
THINKING
If I give you 50 m/s and 50 m/s going North……the number is the same……….velocity just adds the _______________
