An object is traveling in a straight line in space. No forces are affecting it. What will happen to the object's motion?

• It will move faster and faster because there is no force to stop it.

• It will not change. It will continue in the same direction at the same speed.

• It will stop immediately when the force that started its motion goes away.

• It will gradually stop because there is no force to keep it moving.

Which action would require a pulling force.

• Dragging a garbage can

• Kicking a soccer ball

• Closing the refrigerator

• Pushing someone on a swing

Why does a bowling ball require more force to move than a soccer ball?

• It has the most mass

• It is thrown indoors

• A bowling ball is held in your hand. A soccer ball is kicked.

• A bowling ball is smoother than a soccer ball.

Which of these surfaces will friction be the greatest when a block of wood slides across it?

• Smooth wood

• A mirror

• Wet ice

• Sand paper

Mary is pushing her younger brother, Colton, in his toy car. Colton gets out of the car. Colton's friend, who has more mass than he does, gets into the car. If Mary wants to make the car go the same distance that it did when she pushed Colton, what should she do?

• Push the car with less force

• Push the car with more force

• Push the car with the same amount of force

• Add more mass to the car and push it with the same force

Peter applied 15 N of force to each object. Assume friction experienced by each object is the same. Which object will travel farthest?

• A metal disk with a mass of 1.7g

• A rock with a mass of 10g

• A brick with a mass of 45g

• A wooden block with a mass of 9g

How can a small force cause a large mass to move?

• The direction of the force is important in if the object can move

• A small force increases the amount of friction on an object

• A small force balanced the forces that were keeping the rock in place and caused it to move

• A small additional force can cause the forces on an object to become unbalanced resulting in movement
