Energy and Physics Questions

Potential energy is involved before the ball is thrown because:

• it is stored in the ball due to its position.

• it is converted into kinetic energy when thrown.

• it is not involved at all.

• it is only present when the ball is moving.

This picture is an example of kinetic energy because:

• it shows an object in motion.

• it depicts potential energy.

• it illustrates thermal energy.

• it represents chemical energy.

At what point does the ball have the greatest kinetic energy?

• When the ball is released

• When the ball hits the ground

• When the ball is in the air

At what point does the ball have the least kinetic energy?

• When the ball is released

• When the ball hits the ground

• When the ball is in the air

Energy transfers between the pitcher and the ball during the pitch.

• The pitcher applies force, transferring kinetic energy to the ball.

• The ball absorbs energy from the air, increasing its speed.

• The pitcher's energy is converted into potential energy in the ball.

• The ball generates its own energy during the pitch.

The mass of the ball affects the energy of the ball by:

• Increasing the mass increases the energy

• Increasing the mass decreases the energy

• Mass has no effect on energy

• Energy is independent of mass

How does the height the ball is thrown from affect the kinetic energy of the ball?

• The higher the height, the greater the kinetic energy when it hits the ground.

• The height does not affect the kinetic energy of the ball.

• The lower the height, the greater the kinetic energy when it hits the ground.

• Kinetic energy is only affected by the mass of the ball.

If the pitcher used more force during the throw, the ball's speed would:

• Increase

• Decrease

• Stay the same

• Vary unpredictably

What would happen to the ball’s kinetic energy if air resistance were increased significantly?

• The kinetic energy would increase.

• The kinetic energy would decrease.

• The kinetic energy would remain the same.

• The kinetic energy would fluctuate.

Potential energy depends on

• mass and height

• height and speed

• mass and speed

• height and force
