# Kinetic energy and potential energy formula

## Potential and Kinetic Energy

be in many forms! Here we look at Potential Energy (PE) and Kinetic Energy ( KE). v = m/s. Note: for velocity we can combine the formulas like this.

Having gained this energy during its acceleration , the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest. In relativistic mechanics , this is a good approximation only when v is much less than the speed of light. The standard unit of kinetic energy is the joule , while the imperial unit of kinetic energy is the foot-pound. The dichotomy between kinetic energy and potential energy can be traced back to Aristotle 's concepts of actuality and potentiality. Willem 's Gravesande of the Netherlands provided experimental evidence of this relationship.

In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The term potential energy was introduced by the 19th-century Scottish engineer and physicist William Rankine , [3] [4] although it has links to Greek philosopher Aristotle 's concept of potentiality. Potential energy is associated with forces that act on a body in a way that the total work done by these forces on the body depends only on the initial and final positions of the body in space. These forces, that are called conservative forces , can be represented at every point in space by vectors expressed as gradients of a certain scalar function called potential. Since the work of potential forces acting on a body that moves from a start to an end position is determined only by these two positions, and does not depend on the trajectory of the body, there is a function known as potential that can be evaluated at the two positions to determine this work.

An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly, a drawn bow is able to store energy as the result of its position. When assuming its usual position i.

When an object falls, its gravitational potential energy is changed to kinetic energy. You can use this relationship to calculate the speed of the object's descent.

Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. There are many forms of kinetic energy - vibrational the energy due to vibrational motion , rotational the energy due to rotational motion , and translational the energy due to motion from one location to another. To keep matters simple, we will focus upon translational kinetic energy. The amount of translational kinetic energy from here on, the phrase kinetic energy will refer to translational kinetic energy that an object has depends upon two variables: the mass m of the object and the speed v of the object. The following equation is used to represent the kinetic energy KE of an object.
