What does the law of conservation of energy state?

• Energy cannot be created or destroyed, only transferred or transformed.

• Energy can be both created and destroyed.

• Energy can be destroyed but not created.

• Energy can be created but not destroyed.

What is potential energy?

• The energy possessed by an object due to its motion.

• The energy possessed by an object due to its color.

• The energy possessed by an object due to its position or condition.

• The energy possessed by an object due to its temperature.

What is kinetic energy?

• The energy possessed by an object due to its motion.

• The energy possessed by an object due to its shape.

• The energy possessed by an object due to its temperature.

How do you calculate potential energy?

• potential energy = force * distance

• potential energy = mass * acceleration * height

• potential energy = mass * gravity * height

• potential energy = mass * gravity * distance

How do you calculate kinetic energy?

• KE = mass * velocity

• KE = 1/2 * mass * velocity^2

• KE = 1/2 * mass * acceleration^2

• KE = mass / velocity^2
