Physical science?

Physical science is a branch of science that studies the natural world and the physical properties of matter and energy. Work, energy, and power are concepts within physical science that relate to the motion and interactions of objects.

Work is defined as the transfer of energy that occurs when a force is applied to an object and the object moves in the direction of the force. The amount of work done is equal to the force applied multiplied by the distance the object moves.

Energy is the ability to do work, and it comes in various forms such as kinetic energy (energy of motion) and potential energy (stored energy). The total energy of a system remains constant, but it can be transferred between different forms.

Power is the rate at which work is done or energy is transferred. It is calculated by dividing the amount of work done by the time it takes to do that work. Power is measured in watts, with one watt equal to one joule of work done per second.

Understanding the concepts of work, energy, and power is essential in physical science as they help explain the behavior of objects and systems in motion. These concepts are fundamental in fields such as physics, engineering, and technology.
