Andrea is pushing a box on her driveway into her garage. She discovers that the box is hard to move. What could be a reasonable conclusion why the box is hard to move?
The friction between the box and the driveway
The motion of the box
The way gravity affects the box
The driveway is too smooth
Which of the following would increase the motion of a ball after it is kicked?
A rocky surface

A long, round balloon is fastened to the end of a toy rocket. When the balloon is blown up and released, the rocket launches into the air. Which force causes the rocket to launch?
The air released from the balloon
The weight of the rocket
The pull of gravity on the rocket
The mass of the balloon
Which would be needed to make a ball at the base of a ramp move up the ramp?
Gravity
Inertia
Force
Friction
Which factor is most helpful in lowering an object with the use of a pulley?
Friction, because it makes the object move at a constant rate
Gravity, because it allows the object to resist any change
Friction, because it helps speed up the object's movement
Gravity, because it pulls down on the object

What happens when a ball rolls down a hill?
What happens when a moving wagon comes to a stop?
What happens when a person pushes on a large brick wall?
What happens when a bat is used to hit a ball?
When Anna tells her father that her bicycle is hard to pedal, he oils the chain. How does this make her bike easier to ride?

Friction in the bike has increased.
Gravity on the bike has decreased,
Gravity on the bike has increased
Friction acts in a direction __________ to the direction of an object's motion
Unrelated
Opposite
Equal
Perpendicular
Unless an object at rest is acted upon by a force, it stays at rest due to its

Friction
Gravity
Jake and Tom want to see who is strongest, so they got a rope and decided to play tug-o-war. Both boys pulled at the rope with all of their strength, but neither of them moved. This is called unbalanced force.
True
False
Which statement best describes weight?
A measure of the amount of matter inside an object
A measure of any acceleration acting on an object
A measure of the force of gravity acting on an object
A truck is traveling 70 mph with a heavy load in its trailer. After the truck is unloaded, it again travels 70 mph. Which best explains how the force acting on the truck changed after the truck was unloaded?
A smaller force was needed to move the truck because it had less mass
A larger force was needed to move the truck because there was more friction
A smaller force was needed to move the truck because there was less friction
A larger force was needed to move the truck because it had less mass
An airplane traveled 400 miles in one hour. By the end of the next hour, it had traveled a total of 800 miles. Which best describes the motion of the airplane?
It was moving at a faster speed during the second hour.
It was moving at the same average speed for the two hours.
The airplane stopped moving between the first and second hours.
It was moving at a faster speed during the first hour,
In order for someone to push a heavy box 20 feet across the floor, which of the following must happen?
