Energy Power Formula Physics ~ The equation used to calculate the power is. Power formula can be rewritten using ohms law as p i2r or p v2 r. Potential energy of the spring. In the international system of units the unit of power is the watt equal to one joule per second. Power work time or p w t. It is the work time ratio. In physics we can define energy as the capacity to do work. Power is a rate at which work is done or energy is used. Power is a scalar quantity. Where v is the potential difference i is the electric current r is the resistance and p is the electric power. Indeed lately is being sought by consumers around us, maybe one of you. People now are accustomed to using the internet in gadgets to view image and video data for inspiration, and according to the title of this article I will discuss about Energy Power Formula Physics. Power can be defined as the rate at which work is done i e. Hope you have understood about electric energy and power how it is defined its symbol units formula terms. P power w or j s. The kinetic energy k 1 2 mv 2 of each mass element of the string of length δ x is δ k 1 2 δ m v y2 as the mass element oscillates perpendicular to the direction of the motion of the wave. Power rate of doing work if under a constant force f a body is displaced through a distance s in time t then the power p but v uniform velocity with which body is displaced. Ep 1 2 k x k is the spring constant and x is the amount of compression or streching. Pe mg h m is the mass g is the gravitational acceleration and h is the distance. Potential energy of the spring. Ek 1 2mv m is the mass v is the velocity. So the more powerful a device is the more energy it will transfer each second.
Power is a scalar quantity. In older works power is sometimes called activity. So the more powerful a device is the more energy it will transfer each second.
Power work time or p w t.
The equation used to calculate the power is. Ep 1 2 k x k is the spring constant and x is the amount of compression or streching. Power frac work done time taken. Power work time or p w t.
