Physics formula of energy. It is the sum total of potential energy and kinetic energy which is the energy associated with the motion position of any object. The formula for power is. Energy of a photon.

In physics we can define energy as the capacity to do work. Mechanical energy kinetic energy potential energy. Wavelength of a photon.

Pe mg h m is the mass g is the gravitational acceleration and h is the distance. In case of gravitational force the potential energy is given by. The law of conservation of energy states that energy can be converted in form but not created or destroyed.

Ep 1 2 k x k is the spring constant and x is the amount of compression or streching. Momentum p is the product of mass m and velocity v. For the potential energy the formula is.

The energy of a wave formula consider a sinusoidal wave as shown in the figure. Therefore the formula of mechanical energy will be. W work done f force x d displacement energy can be broadly classified into two types potential energy and kinetic energy.

Dimensional formula is ml t 2. Physics data booklet 7. The si unit of energy is the joule which is the energy transferred to an object by the work of moving it a distance.

H planck s constant. The formula for the energy of motion is ke 5 m v 2 where ke is kinetic energy in joules m is mass in kilograms and v is velocity in meters per second. Energy is a conserved quantity.

C speed of light. When a force f moves an object through a distance s which is at an angle of θ then work w is done. The components of the energy are kinetic and potential.

The energy of a wave depends on the amplitude and the frequency of it. The energy that an object has on account of its motion is called ke. Power can be defined as the rate at which work is done i e.

Potential energy of the spring. Ek 1 2mv m is the mass v is the velocity. The law of conservation of energy is one of the basic laws of physics.

The si unit of energy is joules j which is named in honour of james prescott joule. Equations applied to uniform motion known as suvat equations. In physics energy is the quantitative property that must be transferred to an object in order to perform work on or to heat the object.
