Physics Formulas Work And Power

The SI unit of energy is joules J which is named in honour of James Prescott Joule. Now let us look at the formulas that differentiate work from power.

Pin On Physics Formulae

It is defined as the product of the force applied to the object and the distance it travels in the direction which is parallel to the direction of the force.

Physics formulas work and power. Imagine you are pushing a heavy box across the room. Power can be defined as the rate at which work is done ie. K is the spring constant and x is the amount of compression or streching.

Potential Energy of the Spring. Power is useful for your CBSE ICSE board exam as well as for entrance exam like JEE. PEmgh m is the mass g is the gravitational acceleration and h is the distance.

For the potential energy the formula is. Physics Formulas Work Power EnergyCheatsheet. Potential Energy of the Spring.

Physics Formulas Work Power EnergyCheatsheet. Total Work Done W Power P x Time t Or. 24012019 In physics we can define energy as the capacity to do work.

It is represented by the letter W. Power is measured in joules per second Js r o watts W and is worked out using the formula. The hiker has a greater power rating than the rock climber.

These physics formula sheet for chapter Work Energy. Component of force along displacement. Analysis of Situations Involving External Forces.

Force is equal to the mass of an object multiplied by its acceleration so the force is F ma. Moreover it is a very important thing that allows us to see the rate at which electrical energy transfers from an electric circuit. Power from the link given below.

Lesson 2 - The Work-Energy Relationship. Power is the rate at which work is done. Download the Pdf of class 11 physics formula sheet of chapter Work Energy.

If W is work F the force and x the distance then. Power Distance Power Force. Therefore the work done by the force on an object is equal to the change in the objects kinetic energy W K 2 -.

In Physics power is associated with energy and has a precise meaning. Definition and Mathematics of Work. It is a scalar quantity.

Work Force x Displacement cos Fd cos Here is the angle between force and displacement Power P Total Work Done W Time t It would be easy for you to distinguish between work and power when you study the difference between work and power in tabular form. Component of displacement along force. The further you move the more work you do.

20072020 This would in turn allow the car to travel faster. The quantity that has to do with the rate at which a certain amount of work is done is known as the power. Thus it helps us in measuring the efficiency of the same.

Power Work done J Time taken s Simplified formula. W Force. Lesson 1 - Basic Terminology and Concepts.

Here we will try to understand the definition of Work Energy and Power. It is the worktime ratio. Watt W Power.

M is the mass v is the velocity. Formula Sheet for Work Energy Power. Work done by constant force.

The formula for power is. Power Work time or P W t. W FS cos θ θ is angle between F and S W F S Sr2-r.

Force Time. Power is mathematically defined as the work done divided by the time taken. Calculating the Amount of Work Done by Forces.

It is the rate of work done or rate of energy transfer. This formula for force can be substituted in to the formula for work W Fd. PEmgh m is the mass g is the gravitational acceleration and h is the distance.

Unit of work is N-m or J joules. Work is the product of force and the distance over which it moves. The concept of power is concerned with how rapidly energy is being transferred or transformed when work is done.

23102019 Electric Power Formula Electric power is a widely used term in physics as you must be aware of. Distance Time Work Force. Work Energy and Power.

Mathematically it is computed using the following equation. K is the spring constant and x is the amount of compression or streching.
