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

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 _______________
