Thus to help you with that, Embibe offers free Class 9 Science Practice Questionsand Class 9 Science Mock Tests which can be accessed for free. Work is usually introduced in Class 9, thus it’s crucial to master all of Class 9’s Physics topics since it creates a firm basis if you want to pursue Science as a career path. Now that you are provided with all the necessary information about work. Work done can be zero even when force and displacement are perpendicular to each other. \(\therefore \,\,\,\,W = F \times s \times \)Īns.Work done can be zero when either of force or displacement or both are zero. If the displacement is not in the direction of force and, it is making an angle \(\theta \) with the direction of force, then work can be written as, Thus, the work done can be calculated by the below formula, Work done \(\left( W \right)\) is the product of the force \(\left( F \right)\) and the displacement \(\left( s \right)\) in the direction of the force. Work Definition in Physics: The work done by a force acting on an object is equal to the product of the force and the displacement in the direction of the force. Work is said to be done when the force acts on an object, which displaces it in the direction of the force. Therefore, if work needs to be done, then it requires both force and displacement to be non-zero. So, according to Physics, we have not done any work on the wall as there is no displacement in the wall. But the wall does not move or undergo any displacement.

Now, let us push the wall with all our might. In this case, also, we have done some work. Similarly, when we lift a box to some height, we have displaced the box due to the force applied to it which is greater than or equal to the weight of the box. So, according to Physics, we have done some work. This is because the table has undergone displacement due to the force applied to it. For example, when we push a table lying on the floor, it moves to another position. Displacement, on the other hand, is the shortest distance between the initial position and the final position of the body in motion.Įxample: Work is said to be done when the force applied to a body displaces the body in its direction.
