What effect does friction tend to have on an object's motion?
it slows an object's motion
it has no effect on an object's motion
it makes an object start moving
it makes an object move faster
If an object is not moving, what can a force do to it?
increase its mass

A student uses a bat to hit a softball with a certain force. Then she hits a heavier ball with the same force. How does the heavier ball move comparted with the lighter softball?
faster & farther
faster & not as far
more slowly & farther
more slowly & not as far
A student pulls four classroom objects with the same amount of force. On which object's motion will the pull have the greatest effect?
desk
chair
pencil
textbook
How does the distance between objects affect the force of gravity between them?
the greater the distance, the greater the force of gravity
the smaller the distance, the greater the force of gravity
the smaller the distance, the smaller the force of gravity

it reduces the object's speed
it increases the object's speed
it reverses the objects direction
it has no effect on the object's motion

the ball will move faster and farther when your friend kicks it
the ball will move faster and farther when you kick it
the ball will move more slowly and farther when you kick it
the ball will move faster and not as far when your friend kicks it
A scientist drops two objects from the same height. One object is a metal ball, and the other is a plastic ball. Both objects are the same size but have different weights. The scientist observes that both balls hit the ground at the same time. What force is responsible for this result, and why does it happen?
Gravity pulls on both objects equally, regardless of their weight
Friction slows down the lighter object
Air resistance pushes both objects downward
Magnetism attracts the heavier ball to the ground faster
Why do parachutes slow down a skydiver?
Gravity stops working
Friction between the air and the parachute slows their fall
The parachute makes them heavier
The parachute increases their speed
A ball is thrown in the air. As it rises, it slows down until it stops and then begins to fall back to the ground. Which two forces are working together to change the ball's motion, and how do they work?
Friction slows the ball, and air resistance pushes it higher
Gravity pulls the ball back down, and air resistance slows its motion upward
Magnetism pulls the ball upward, and gravity slows it down until it hits the ground and stops
Friction and gravity work together to push the ball higher
If you roll a ball on the grass and on a smooth floor, what happens?

A kite floating in the sky
A ball rolling down a hill
A car slowing down on a flat surface
A magnet attracting a nail
What happens if you roll a ball on a perfectly smooth and flat surface with no friction?
the ball would roll forever
the ball would stop quickly
the ball would bounce
the ball would roll slower and slower

A toy car is placed at the top of a ramp and allowed to roll down. The ramp is covered with different materials: smooth plastic, rough sandpaper, and soft carpet. After testing, the car rolls farthest on the smooth plastic. Why does the car roll farther on the smooth plastic?
the smooth plastic has less friction to slow down the car
the ramp is steeper when covered with plastic
the smooth plastic increases the car's weight
the rough materials make the car lighter
A boy rolls a ball across two different flat surfaces with the same amount of force.
The list below describes the motion of the ball on each surface.
Surface 1: The ball rolled one meter in three seconds.
Surface 2: The ball rolled two meters in three seconds.
What could have caused the ball to go farther in the same amount of time on Surface 2?
Surface 1 had less mass than Surface 2.
Surface 1 had more mass than Surface 2.
The ball experienced more friction while rolling on Surface 2.
The ball experienced less friction while rolling on Surface 2.
