Energy and Energy Transfer

Front

What is energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or condition. For example, a ball held at a height 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 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.

Front

What is light energy?

Back

Light energy is a form of energy that travels in waves and can be seen by the human eye. It is produced by sources like the sun and light bulbs.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating objects and is transmitted through air, water, or solids.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object. It is the energy associated with the motion and position of an object.

Front

How does energy transfer occur?

Back

Energy transfer occurs when energy moves from one object or system to another, such as when heat moves from a hot object to a cooler one.

Front

What is an example of energy transformation?

Back

An example of energy transformation is when a toaster converts electrical energy into thermal energy to toast bread.
