Energy stores and systems

What is kinetic energy?

Kinetic energy is the energy possessed by an object due to its motion.

What is potential energy?

Potential energy is the stored energy of an object based on its position or state.

What are the two main types of mechanical energy?

Kinetic energy and potential energy.

What is the law of conservation of energy?

The law states that energy cannot be created or destroyed, only transformed from one form to another.

What is thermal energy?

Thermal energy is the internal energy of an object due to the kinetic energy of its particles.

What is chemical energy?

Chemical energy is the energy stored in the bonds of chemical compounds.

What is elastic potential energy?

Elastic potential energy is the energy stored in objects that can be stretched or compressed, such as springs.

How does gravitational potential energy change?

Gravitational potential energy increases with height and decreases as an object falls.

What is a system in physics?

A system is a defined set of objects or particles being studied, along with the energy and forces acting on them.

What is the difference between closed and open systems?

In a closed system, energy can transfer but not matter; in an open system, both energy and matter can be exchanged.
