Steven holds a book above the floor. He lets go of the book and the book speeds up as it falls to the floor. Which of the following forms of energy are involved in an energy transformation while the book is falling?

Both potential energy and kinetic energy are involved. As the book is falling, its potential energy decreases and its kinetic energy increases.

Kinetic energy is involved but potential energy is not. As the book is falling, its kinetic energy increases but its potential energy does not change

Potential energy is involved but kinetic energy is not. As the book is falling, its potential energy decreases but its kinetic energy does not change.

Neither potential energy nor kinetic energy is involved. Potential energy cannot be changed into kinetic energy, and kinetic energy cannot be changed into potential energy.

Consider the following situations:

Situation 1: A cold spoon is placed in a cup of hot tea. Situation 2: A spring is used to roll a ball across the floor.

Is energy being transferred in either of these situations?

Energy is transferred in both situations.

Energy is NOT transferred in either situation.

Energy is transferred when a cold spoon is placed in a cup of hot tea, but energy is NOT transferred when a spring is used to roll a ball across the floor.

Energy is transferred when a spring is used to roll a ball across the floor, but energy is NOT transferred when a cold spoon is placed in a cup of hot tea.

A ball, starting from rest at Position 1, rolls along a curved track toward Position 5. The ball speeds up as it rolls from Position 1 to Position 3, and it slows down as it rolls from Position 3 toward Position 5. Just before it reaches Position 5, it stops and rolls back down the track. As the ball rolls back and forth along the curved track, the ball and the track get a little warmer.

When does the thermal energy of the ball and track increase and why?

Only when the ball rolls from Position 1 to Position 3 because the gravitational potential energy of the ball is converted into thermal energy

Only when the ball rolls from Position 3 toward Position 5 because the kinetic energy of the ball is converted into thermal energy

The thermal energy increases the entire time the ball is rolling along the track because both the gravitational potential energy and kinetic energy of the ball are converted into thermal energy.

The thermal energy increases the entire time the ball is rolling along the track, but the increase does not come from a change in gravitational potential energy or kinetic energy because kinetic energy and gravitational potential energy cannot be converted into thermal energy.
