• Friction

• Contact force

• Air resistance

• Gravity

Choose the best answer for each item. Why is it harder to push a heavy box than a light one on the same floor?

• Gravity only affects heavy objects

• Heavy objects have more friction

• Light objects are pulled by friction

• Friction makes objects lighter

• Looking at the sky

• Floating a paper boat in water

Choose the best answer for each item. When you slide a coin across a table, it will eventually stop. What makes it stop?

• The shape of the coin

• The direction of the push

• The force of friction

• The weight of the coin

Choose the best answer for each item. If there were no friction, what would happen to a ball you kicked?

• It would bounce up

• It would stop immediately

• It would roll forever

• It would change shape

Choose the best answer for each item. What could you do to make a toy car roll farther on a surface?

• Add more weight on it
