Can the work done be negative
WebWork done by a force on a body can be positive, negative and zero i.e., (a) Work done is positive :- Force is in the same direction as displacement for example work done by force for pushing a block of mass m (b) Work done is negative :- Force is opposite to the displacement for example when a body slides on horizontal surface work done by ... Web2 days ago · Negative Work: When force & displacement are in reverse directions, then the work is assumed to be negative. For instance, when a ball is thrown upwards, the displacement will be in upwards direction; however, the force because of the gravity of the earth will be in the downward direction.

WebCan the work done be negative? Watch the video and find out! Unit of Work. The SI unit of work is Joule (J). For example, if a force of 5 newtons is applied to an object and moves 2 meters, the work done will be 10 newton-meter or 10 Joule. It should be noted that 1 J = 1 N ⋅ m = 1 kg ⋅ m 2 /s 2. WebWork is a measurement of energy, so it may seem odd to think that a work can be negative — but it can! Work is how much energy is done by a force over a distance.
