Work-Energy Principle

Definition

The work-energy principle states that the work done on an object equals its change in kinetic energy. It relates the concept of work, which is the transfer of energy through force, to changes in an object's motion and energy.

Work:

Work is defined as the product of force and displacement in the direction of that force. It quantifies how much energy is transferred to or from an object due to applied forces.

Kinetic Energy:

Kinetic energy is the energy possessed by an object due to its motion. It depends on both mass and velocity and can be changed by doing work on or by non-conservative forces acting upon it.

Potential Energy:

Potential energy refers to stored energy that results from an object's position or condition. Examples include gravitational potential energy and elastic potential energy.
