Answer» Inphysics, aforceis said to doworkif, when acting, there is adisplacementof the point of application in the direction of the force. For example, when a ball is held above the ground and then dropped, the work done on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement). When the force is constant and the angle between the force and the displacement is θ, then the work done is given byW=Fscos θ. hit like if you find it useful |
