A woman gets in an elevator at the top of the Empire State Building and descends toward the ground floor. What happens to the woman's potential energy as she descends?

As height decreases, the woman's potential energy will decrease.

As height decreases, the woman's potential energy will increase.

As height decreases, the woman's potential energy will stay the same.

It is impossible to tell because we don't know the height the woman started at.

An airplane traveling at a constant altitude loses mass as it uses up jet fuel. What happens to the plane's potential energy as it uses up fuel?

As mass decreases, the plane's potential energy will decrease.

As mass decreases, the plane's potential energy will increase.

As mass decreases, the plane's potential energy will stay the same.

It is impossible to tell because we don't know the height of the plane.

It is impossible to tell because we don't know the acceleration due to gravity.

What is the best representation of the law of conservation of energy?

Energy can not be created or destroyed. It can only change forms.

Potential energy is always conserved.

Energy can only change between potential and kinetic forms of energy.

United States citizens must conserve energy to reduce our impact on the environment.

Energy is conserved when forces are balanced.

A person sits at the top of a waterslide. Which of the following is the best description of the person's energy as he or she travels down the slide?

Potential energy is converted to kinetic energy. Total energy remains constant.

Kinetic energy is converted to potential energy. Total energy remains constant.

Kinetic energy is converted to potential energy. Total energy increases.

Potential energy is converted to kinetic energy. Total energy increases.

Kinetic energy is converted to potential energy. Total energy decreases.

Two teams play a game of tug-of-war. If the blue team wins by pulling the black team to the right, which statements are true? Select all answers that apply.

The force acting to the right is stronger.

The forces between the two teams are unbalanced.

The forces between the two teams are balanced.

The force acting to the left is stronger.

Centrifugal force is pulling the two teams apart.

Which of these statements are true about energy and work?

Energy is the ability to do work.

Energy is measured in joules; work is measured in newtons.

Energy is work acting at a distance.

Energy is stored; work is used.

Energy depends on force; work depends on mass.

A cheetah chasing an antelope increases its velocity to catch the antelope. Assuming the mass of the cheetah stays the same, what happens to the cheetah's kinetic energy as it increases velocity?

As velocity increases, the cheetah's kinetic energy will increase.

As velocity increases, the cheetah's kinetic energy will stay the same.

As velocity increases, the cheetah's kinetic energy will decrease.

It is impossible to tell because we don't know the mass of the cheetah.

It is impossible to tell because we don't know the velocity of the cheetah.
