Motion
How fast an object is traveling over a given distance.
A) Acceleration
B) Speed
C) Distance
B) speed?
The less mass an object has, the less of this is needed to move it.
A) Force
B) Gravity
C) Resistance
What is A) force?
A force that that pulls objects to the center of the earth.
What is gravity?
An example of this force can be observed during a kickball game when the ball is pitched, but the force between the ball and the ground makes the ball stop before reaching the kicker.
What is friction?
Which of the following will have the least motion?

B) An object with a large mass being pushed with a small force
C) An object with a large mass being pushed with a large force
D) An object with a small mass being pushed with a large force
B) An object with a large mass being pushed with a small force
A change in speed or direction.
A) Acceleration
B) Distance
C) Time warp
What is A) acceleration?
An object in motion will stay in motion, and an object at rest will stay at rest, unless acted upon by a(n) ____________ force.
A) Balanced
B) Unbalanced
What is B) unbalanced?
When two objects rub together, they create this force.
A) Static
B) Energy
C) Friction
What is C) friction?
Which of these is a unbalanced force?
A) Sitting in your chair
B) Falling out of your chair
C) A tie in tug of war

A moving object will do this when friction is increased.
A) Speed up
B) Slow down
C) Nothing
What is B) slow down
If a ramp is steeper, will it cause the object rolled down it to go faster or slower?
Faster
If a kid pulls back further on a sling shot, the object launches further. Why is this?
There is a greater force
To find this use the formula distance/time (d divided by t)
A) Acceleration
B) Speed
C) Distance Traveled
What is B) speed?
If equal forces are balanced on an object, then this will happen with the object.
A) It will move
B) It will accelerate
C) No movement
What is C) NO movement?
This is the result when weight is added to a vehicle and the force is not increased.
What is slow down or reduce speed?
What 2 things affect how fast an object falls if dropped from the top of a tower?
What is air resistance and gravity?
If I drive 200 miles in 4 hours, what is my average speed?
50 mph
In order to start something moving, this must be applied to the object.
A) A push

C) A push or a pull
What is an C) A push or a pull
For every action, there is an _____________ and ___________ reaction.
What is equal and opposite
If a car is traveling 60 mph per north and then turns right and continues driving 60 mph, is this acceleration?
Yes- because there was a change in direction
