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 more.

Front

What are the different forms of energy?

Back

The main forms of energy include kinetic energy, potential energy, thermal energy, chemical energy, electrical energy, nuclear energy, and radiant energy.

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy of an object in motion, calculated using the formula: KE = 0.5 x mass x velocity².

Front

What is Potential Energy?

Back

Potential energy is stored energy based on an object's position or state, such as gravitational potential energy, which depends on height.

Front

What is the formula for calculating Kinetic Energy?

Back

The formula for calculating Kinetic Energy is: KE = 0.5 x mass x velocity².

Front

What is the difference between Kinetic and Potential Energy?

Back

Kinetic energy is energy of motion, while potential energy is stored energy based on position or condition.

Front

What is the Electromagnetic Spectrum?

Back

The Electromagnetic Spectrum is the range of all types of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is Radiant Energy?

Back

Radiant energy is the energy of electromagnetic waves, such as light, and is associated with the movement of photons.

Front

What are Infrared Waves?

Back

Infrared waves are a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves, commonly associated with heat.

What is the Crest of a Wave?

Back

The crest is the highest point of a wave, representing the maximum displacement of the wave from its rest position.
