Potential/kinetic energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

What does the law of conservation of energy state?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

At what point in a pendulum's swing is potential energy greatest?

Back

Potential energy is greatest at the highest points of the swing.

Front

At what point in a pendulum's swing is kinetic energy greatest?

Back

Kinetic energy is greatest at the lowest point of the swing.

Front

What energy transformation occurs when a battery powers a flashlight?

Back

Chemical energy in the battery is transformed into electrical energy, which is then transformed into light energy.

Front

What is an example of potential energy?

Back

A rock held at the top of a hill has potential energy due to its height.

Front

What is an example of kinetic energy?

Back

A moving car has kinetic energy due to its motion.

Front

How is potential energy calculated?

Back

Potential energy (PE) is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How is kinetic energy calculated?

Back

Kinetic energy (KE) is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.
