Revision notes on work power and energy.
Work power energy formulas class 11.
Here 1 4πσ 0 9 0 10 10 n m 2 c 2 constant.
A collision in which the total kinetic energy of the system is conserved is called elastic.
It is measured by the product of the force and the distance moved in the direction of the force i e w f s.
Where k i.
We at byju s are of the opinion that proper guidance with the right textbooks is essential for students to succeed.
1 watt 1 joule second.
Check the physics formula list for class 11 given below.
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 energy and power class 11 notes thus we have discussed three elementary topics on physics as students would have covered them during their high school days.
Work done by a force in displacing a body is equal to change in its kinetic energy.
Dimensions of power linear momentum of an isolated system is always conserved in a collision.
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.
Free pdf download of physics class 11 chapter 6 work energy and power formula prepared by subject expert teacher at vedantu.
Power is the rate at which work is done or energy is transformed.
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.
Before moving to physics.
The physics formulas for class 11 pdf is provided here so that students can understand the subject more effectively.
Work work done w is defined as the dot product of force f and displacement s.

The unit of power is watt.
Work power and energy.
Work done by the force is positive if the angle between force and displacement is acute 0 θ 90 as cos θ is positive.
U 1 4πσ 0 q 1 q 2 r.
It is a scalar quantity.
Here θ is the angle between and.
