F
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.
A) Speed
B) Gravity
C) A mother's love
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?
A) An object with a small mass being pushed with a small force
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
A change in speed or direction.
A) Acceleration/deceleration
B) Distance
C) Time warp
What is A) acceleration/deceleration?
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 non contact force?
A) Push
B) Gravity
C) Slide
B) Gravity
Why can you roller skate faster on a roller rink than in a parking lot?
There is less friction
Which of these has the most friction
A) Sandpaper
B) Ice
C) Parking lot

If I drive 50 MPH for 4 hours, how far will I travel?
200 miles
A moving object will do this when friction is increased.
A) Speed up
B) Slow down
C) Nothing
What is B) slow down or stop?
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 (for example: miles/hour)
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. (Think...the vehicle is traveling on a flat surface.)
What is slow down or reduce speed?
Two objects of different masses are dropped from the same height/altitude at the same time. They will hit the ground in which order.
A) Object with the larger mass first, then the object with the smaller mass
B) Object with the smaller mass first, then the object with the larger mass
C) Both objects will hit the ground at the same time
What is at the same time?
Is air resistance a contact or non-contact force?
contact
In order to start something moving, what type of force must be applied to the object.
A) Any type of force
B) A balanced force
C) An unbalanced force
What is an C) unbalanced force?
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
An object has traveled 420 miles in 7 hours. What was the average mileage per hour (speed per hour)?
What is 60 miles per hour?
Calculate the speed of a car if it goes 325 miles in 5 hours.
65 mph
