A moving car walking up stairs lifting heavy objects an aeroplane flying etc are among the most common examples that give us insight into the concept of work power and energy.
Learning the important concepts is very important for every student to get better marks in examinations.
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 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.
It is measured by the product of the force and the distance moved in the direction of the force i e w f s.
