Shari is using two toy cars to experiment with force and motion. The cars have different masses. Car A has a mass of 100 grams. Car B has a mass of 300 grams. Shari pushes each car forward using the same amount of force. Which car will travel farther?

• Car A will travel farther.

• Car B will travel farther.

• The cars will travel at the same distance.

• It is not possible to predict which car will travel farther.

As part of a science project, Samuel slides several different objects down a ramp. The objects Samuel uses are a magnet, a marble, a wooden block, and a metal car. Which two forces are acting on all the objects as they slide down the ramp?

• Gravity moves the objects, and friction slows them down.

• Friction moves the objects, and gravity slows them down.

• Magnetism moves the objects, and gravity slows them down.

• Gravity moves the objects, and a pulling force slows them down.

Stephanie started pushing a bookcase across the room, as shown in picture 1. Then, she removed the books and continues pushing with the same force and direction in picture 2. How does removing the books affect the motion of the bookcase?

• The mass is decreased, making the bookcase move faster.

• The gravity is increased, making the bookcase move slower.

• The friction is increased, making the bookcase move slower.

• The mechanical energy is decreased, making the bookcase move faster.

Mr. Brown gave Jen's lab group a ramp and a toy car. He placed large sheets of waxed paper, plastic wrap, glass, and artificial grass on a table. The group was asked to cover its ramp with the material they thought would slow down the car the most. Which material should they use?

• artificial grass

• glass

• plastic wrap

• waxed paper

Mr. Gates mops the gymnasium floor every day. When he finishes mopping, he puts up the sign below. The effect of which force is weakened when the floor is wet?

• friction

• gravitation

• inertia

• magnetism

Mrs. Smith set up four ramps. The ramps had the heights shown here. Mrs. Smith held up a toy car. She explained that the students were going to determine if ramp height affects how far a car travels in 15 seconds. The students were told not to push the cars down the ramp. What force can the students use to move the cars down the ramp?

• pull

• gravity

• friction

• magnetism
