The law of conservation of energy describes how the amount of total energy can change in a closed system. Which of these statements correctly describes this law?

• The amount of kinetic energy in a system is a constant value.

• Energy can be converted from one form into another, but it cannot be created or destroyed.

• An object can have potential energy or kinetic energy, but not both at the same time.

• The amount of energy created when an object moves is equal to the energy destroyed when it stops moving.

• All of the above 

Which of the following demonstrates an airplane converting kinetic to potential energy?

• It ascends to a higher altitude.

• More passengers board the plane.

When a roller coaster is at the top of a hill it has

• high potential energy

• high kinetic energy

• low potential energy

• equal amounts of kinetic and potential energy

When a roller coaster is at the bottom of a hill it has

• high potential energy

• high kinetic energy

• low kinetic energy

Energy is always conserved. It cannot be created or destroyed. It can, however, be transferred between objects or systems, from one form to another. Which of the following is true of the relationship between kinetic and potential energy?

• When a system loses kinetic energy, it loses potential energy.

• As kinetic energy decreases, potential energy decreases.

• When a system gains kinetic energy, it loses potential energy.

• As kinetic energy increases, potential energy increases.
