Show What You Know Category 1 Force Motion Energy Matter

Model:

A student pushes a toy car across a smooth floor. The car starts from rest, moves for a short distance, and then stops.

Question:

Based on the model provided, which of the following statements best describes the relationship between work, force, and motion involved?

• The student applied a force to the car, causing it to move (motion), but no work was done because the car eventually stopped.

• Work was done on the car because the student applied a force that caused the car to move a certain distance. The car's motion was a result of this force and work.

• The car's motion created the force that the student applied, and therefore, work was done.

• Force and motion are the same thing, so work was done as long as the car was moving.

The picture shows a soccer player kicking a ball.

Which statement best explains what happens to the energy after the player kicks the ball?

• A. The energy disappears once the ball moves.

• B. The energy from the player’s leg is transferred to the ball, causing it to move.

• C. The ball creates its own energy as it rolls.

• D. The energy from the ground pushes the ball forward.
