Energy Transformations

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, including kinetic, potential, thermal, and more.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state. For example, a raised object has gravitational potential 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.

Front

What are the two main types of mechanical energy?

Back

The two main types of mechanical energy are kinetic energy and potential energy.

How does energy transform in a roller coaster?

Back

In a roller coaster, potential energy is highest at the top of the track, and as it descends, it transforms into kinetic energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground.

What is an example of energy transformation in a light bulb?

Back

In a light bulb, electrical energy is transformed into light energy and thermal energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

What is an example of kinetic energy in everyday life?

Back

A moving car, a running dog, or a thrown ball are all examples of kinetic energy.
