Work done by the force is equal to the product of the force and the displacement of the object in the direction of force.
Notes for work energy and power chapter of class 11 physics.
Work power and energy are among the most important concepts of mechanics.
Here θ is the angle between and.
Where k i initial kinetic energy.
Regarding the work energy theorem it is worth noting that i if w net is positive then k f k i positive i e k f k i or kinetic energy will increase and vice versa.
This signifies when the force and displacement are in same.
Work done by the force is positive if the angle between force and displacement is acute 0 θ 90 as cos θ is positive.
Work done by a force in displacing a body is equal to change in its kinetic energy.
