What is energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass and velocity of the object, calculated using the formula KE = 1/2 mv².

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state. For example, a rock at the top of a hill has gravitational potential energy.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature. It is often associated with heat.

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 chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or fuel, which can be released during a chemical reaction.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground, calculated using the formula PE = mgh.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is the energy of motion.

Front

What happens to energy during a firework display?

Back

During a firework display, chemical potential energy is converted into kinetic energy, thermal energy, light, and sound.

Front

How does energy transfer occur in a closed system?

Back

In a closed system, energy can transfer between objects but the total energy remains constant, as per the law of conservation of energy.
