Law of Conservation of Energy

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.

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

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

Front

How does energy transform during a roller coaster ride?

Back

As the roller coaster climbs, potential energy increases; as it descends, potential energy converts to kinetic energy.

Front

What happens to energy when a rock falls?

Back

When a rock falls, its potential energy is converted into kinetic energy.

Front

What type of energy does a light bulb convert electrical energy into?

Back

A light bulb converts electrical energy into light energy and heat energy.

Front

What type of energy conversion occurs in muscles?

Back

Muscles convert chemical energy from food into mechanical energy for movement.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height above the ground.

Front

What is an example of energy transformation in a pendulum?

Back

In a pendulum, energy transforms from kinetic energy at the lowest point to potential energy at the highest points.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object that is used to do work.
