Energy and Energy Conversion

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, chemical, and electrical.

Front

What is energy conversion?

Back

Energy conversion is the process of changing energy from one form to another, such as converting electrical energy into thermal energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, such as gravitational potential energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses because of its height above the ground, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, such as light from the sun, which can be converted into chemical energy by plants.

Front

What is mechanical energy?

Back

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

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons, commonly used to power devices.

What is an example of energy transformation in a toaster?

Back

In a toaster, electrical energy is transformed into thermal energy (heat) and light energy.
