Two toy race cars are going to be raced down the same ramp. Which information is most helpful in predicting which car will win the race?
a) length of the ramp
b) volume of the cars
c) slope of the ramp

A mover has to lift a heavy box with a pulley. Which force is the greatest to overcome in order to lift the box?
a) gravity
b) wind
c) friction
d) pressure

Which factor is most helpful in lowering an object with the use of a pulley?
a) friction, because it makes the object move at a constant rate
b) friction, because it helps speed up the object’s movement
c) gravity, because it allows the object to resist any change
d) gravity, because it pulls down on the object

Which would be needed to make a ball at the base of a ramp move up the ramp?
a) force
b) friction
c) gravity
d) inertia

Which best describes the speed of a ball as it is thrown straight up into the air and comes back down?
a) The ball goes up at a constant speed, stops, then comes down at a constant speed.
b) The ball goes up at a constant speed, stops, and increases speed as it comes down.
c) The ball goes slower and slower as it goes up, stops, and then goes faster and faster as it comes down.
d) The ball goes slower and slower as it goes up, stops, and then comes down at a constant speed.

What is necessary to determine the speed of an object?
a) the mass and volume of the object
b) the shape of the object and the distance it moved
c) the mass of the object and the time it took to move
d) the distance moved by the object and the time it took to move

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?
a) the mass of the balloon
b) the weight of the rocket
c) the pull of gravity on the rocket
d) the air released from the balloon

A girl walked for 30 minutes. She noticed that she traveled farther in the first 15 minutes of her walk than in the second 15 minutes. What can she conclude about her walk?
a) She walked over many hills.
b) Her average speed was faster during the first half of her walk.
c) She walked in two different directions.
d) She was walking at a constant speed.

Which of the following would increase the motion of a ball after it is kicked?
a) a high, grassy surface
b) a surface sloped uphill
c) a surface sloped downhill
d) a rocky surface

Shane and Brett push a toy car on a straight track. When Shane pushes the car, it goes a longer distance than when Brett pushes it. Which best explains this?
a) Brett applied more force to the car.
b) Shane applied more force to the car.
c) Brett did not apply any force to the car.
d) Shane applied the same amount of force as Brett.

Carli is trying to determine if a force can change the direction of an object’s motion. The answer to which question will best help her come to a conclusion?
a) What happens when a ball rolls down a hill?
b) What happens when a bat is used to hit a ball?
c) What happens when a moving wagon comes to a stop?
d) What happens when a person pushes on a large brick wall?

Which is true when equal and opposite forces are applied to an object?
a) The forces combine.
b) There is forward movement.
c) There is no change in motion.
d) The speed of the object increases.

If a small rock and a large rock are both thrown at a wall at exactly the same speed, which rock would most likely cause more damage to the wall?
a) The large rock would cause more damage because it has a greater mass, making the momentum greater.
b) The large rock would cause more damage because the force would be spread out on a larger area.
c) The small rock would cause more damage because it has a smaller mass, making the momentum greater.
d) The small rock would cause more damage because all of the force would be concentrated on one small area.

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?
a) It was moving at the same average speed for the two hours.
b) The airplane stopped moving between the first and second hours.
c) It was moving at a faster speed during the first hour.
d) It was moving at a faster speed during the second hour.

In order for someone to push a heavy box 10 meters across a floor, which must happen?
a) The force of the person pushing must be greater than the force of friction.
b) The force of the person pushing must be less than the force of friction.
c) The force of the person pushing must be less than the force of gravity.
d) The force of the person pushing must be greater than the force of gravity.

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?
a) Friction on the bike has decreased.
b) Friction on the bike has increased
c) Gravity on the bike has increased.
d) Gravity on the bike has decreased.

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) A smaller force was needed to move the truck because it had less mass.
b) A larger force was needed to move the truck because it had less mass.
c) A smaller force was needed to move the truck because there was less friction.
d) A larger force was needed to move the truck because there was more friction.

Which must happen for a moving car to change direction?
a) Another force must act on the car.
b) The car must slow down.
c) The mass of the car must change.
d) Gravity must act on the car.

b) a boy sitting on a chair
c) a dog holding a ball in its mouth
d) marble rolling at a constant speed
