W Fs Where W Work F Constant Force N S Distance moved in the direction of the force. Moreover work and power also discussed in this unit.
It is the worktime ratio.
Physics formula power work. The kinetic energy of an object can be related to its mass and velocity with the formula This formula for kinetic energy can be found from the equation for work if the force is in the same direction as the objects displacement. M is the mass v is the velocity. Power is a rate at which work is done or energy is used.
The standard metric unit of power is the Watt. Knowing how to calculate these measurements in different situations will help immensely in your physics journey as well as your exams. It is equal to the amount of work done divided by the time it takes to do the work.
We will try to give examples related to each topic. 03092020 Power in Physics Formula. Power Distance Power Force.
Moreover it is a very important thing that allows us to see the rate at which electrical energy transfers from an electric circuit. 20072020 The concepts of work and power are crucial in the field of physics. Power is useful for your CBSE ICSE board exam as well as for entrance exam like JEE.
Here is the equation that relates work done force applied and distance moved in the direction of the force. In this unit we will deal with the energy mechanical energy potential energy kinetic energy conservation of energy theorem. These physics formula sheet for chapter Work Energy.
It is the time derivative of work. Mathematically it is computed using the following equation. 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.
P d W d t displaystyle Pfrac dWdt where P is power W is work and t is time. The SI unit of energy is joules J which is named in honour of James Prescott Joule. 23022014 Work is done when a force moves the object in the direction of the force and is given by the product of the force and the distance moved in the direction.
23102019 Electric power is a widely used term in physics as you must be aware of. Similarly you will learn about the electric power formula in detail over here. The unit of power is the Watt W which is equal to a Joule per second Js.
Power Work time or P W t. PEmgh m is the mass g is the gravitational acceleration and h is the distance. Power from the link given below.
Physics Formulas Work Power EnergyCheatsheet. K is the spring constant and x is the amount of compression or streching. Work Power Energy Exams and Solutions.
Power is the rate with respect to time at which work is done. Potential Energy of the Spring. This formula depends on the kinematic formula The change in position x - x 0 is equal to the displacement.
If you need any assistance or want to broaden your understanding of the subject you can engage a reputable physics tuition teacher. Power can be defined as the rate at which work is done ie. For the potential energy the formula is.
Power is the rate at which work is done. P power W or Js W the work done or energy used J t the time taken to do the work s. 24012019 In physics we can define energy as the capacity to do work.
As is implied by the equation for power a unit of power is equivalent to a unit of work divided by a unit of time. Force Time. Workdone force times distance W F times d.
