Mechanical Energy

Definition

Mechanical energy refers to the sum of potential and kinetic energies in a system. It represents the ability to do work due to motion or position.

Analogy

Imagine mechanical energy as a combination lock. The potential energy acts like one number on the lock, while kinetic energy acts like another number. When you have both numbers aligned correctly, you can unlock and use the mechanical energy.

Related terms

Kinetic Energy: The energy possessed by an object due to its motion.

Potential Energy: The stored energy an object has due to its position or condition.

Conservation of Energy: The principle stating that total mechanical energy remains constant in a closed system where no external forces act upon it.
