Work, Power, Energy

Front

Potential Energy

Back

The energy possessed by a body due to its position relative to others, stresses within itself, electric charge, and other factors.

Front

Mechanical Energy

Back

The sum of potential energy and kinetic energy present in the components of a mechanical system.

Front

Kinetic Energy

Back

The energy that a body possesses due to its motion, calculated as KE = 1/2mv².

Front

Work

Back

The energy transfer that occurs when an object is moved over a distance by an external force, calculated as W = Fd.

Front

Power

Back

The rate at which work is done or energy is transferred, calculated as P = W/t.

Front

Joules

Back

The SI unit of work or energy, equivalent to the work done by a force of one newton when its point of application moves one meter in the direction of the force.

Front

Watts

Back

The SI unit of power, equivalent to one joule per second.

Front

Law of the Conservation of Energy

Back

A principle stating that energy cannot be created or destroyed, but can be altered from one form to another.

Front

Force

Back

An interaction that, when unopposed, will change the motion of an object. It is a vector quantity.

Front

W=Fd

Back

The formula for work, where W is work, F is force, and d is distance.
