Law of Conservation of Energy Introduction

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, such as height above the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and velocity.

Front

How is potential energy converted to kinetic energy?

Back

Potential energy is converted to kinetic energy when an object falls or moves from a higher position to a lower position.

Front

What happens to energy during a roller coaster ride?

Back

Energy is continuously converted between potential and kinetic energy as the roller coaster moves up and down.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object possesses due to its height in a gravitational field.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with the mass of an object; if mass increases, kinetic energy increases if velocity remains constant.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is an example of energy transformation in a pole vault?

Back

In pole vaulting, chemical energy from the athlete's muscles is transformed into kinetic energy during the run, then into potential energy as they rise.

Front

What is the relationship between height and potential energy?

Back

The higher an object is, the more potential energy it has due to its position in a gravitational field.
