Work power energy formulas class 11.

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. Before moving to physics. Where k i. It is measured by the product of the force and the distance moved in the direction of the force i e w f s.

Work work done w is defined as the dot product of force f and displacement s. Free pdf download of physics class 11 chapter 6 work energy and power formula prepared by subject expert teacher at vedantu. Here 1 4πσ 0 9 0 10 10 n m 2 c 2 constant. Dimensions of power linear momentum of an isolated system is always conserved in a collision.

Power is the rate at which work is done or energy is transformed. Work power and energy. Separated by a distance r in vacuum is given by. U 1 4πσ 0 q 1 q 2 r.

Work done by a force in displacing a body is equal to change in its kinetic energy. If you have any query regarding ncert solutions for class 11 physics chapter 6 work energy and power drop a comment below and we will get back to you at the earliest. Check the physics formula list for class 11 given below. A collision in which the total kinetic energy of the system is conserved is called elastic.

Academic team of entrancei prepared short notes and all important physics formulas and bullet points of chapter work energy power class 11 physics. 1 watt 1 joule second. 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. This signifies when the force and displacement are in same.

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. Work done by the force is equal to the product of the force and the displacement of the object in the direction of force. Iii electric potential energy the electric potential energy of two point charges ql and q l. Here θ is the angle between and.

It is a scalar quantity. The physics formulas for class 11 pdf is provided here so that students can understand the subject more effectively. Work done by the force is positive if the angle between force and displacement is acute 0 θ 90 as cos θ is positive. The unit of power is watt.
