Work Power Energy Formulas Class 11

Work done by the force is equal to the product of the force and the displacement of the object in the direction of force.

Work power energy formulas class 11.

A collision in which the total kinetic energy of the system is conserved is called elastic. Power is the rate at which work is done or energy is transformed. Work done by a force in displacing a body is equal to change in its kinetic energy. Where k i.

Here θ is the angle between and. Iii electric potential energy the electric potential energy of two point charges ql and q l. Work power and energy. Revision notes on work power and energy.

It is measured by the product of the force and the distance moved in the direction of the force i e w f s. The physics formulas for class 11 pdf is provided here so that students can understand the subject more effectively. 1 watt 1 joule second. We hope the ncert solutions for class 11 physics chapter 6 work energy and power help you.

It is a scalar quantity. The unit of power is watt. Here 1 4πσ 0 9 0 10 10 n m 2 c 2 constant. These list of physic formula of class 11 chapter work energy power is useful and highly recommended for quick revision and final recap of chapter work energy power.

Separated by a distance r in vacuum is given by. Physics notes class 11 chapter 6 work energy and power work when a force acts on an object and the object actually moves in the direction of force then the work is said to be done by the force. Work energy and power class 11 notes physics chapter 6 work is said to be done when a force applied on the body displaces the body through a certain distance in the direction of applied force. Work done by the force is positive if the angle between force and displacement is acute 0 θ 90 as cos θ is positive.

Dimensions of power linear momentum of an isolated system is always conserved in a collision. Work work done w is defined as the dot product of force f and displacement s. This signifies when the force and displacement are in same. U 1 4πσ 0 q 1 q 2 r.
