WebPushing a box through a distance. 2. Lift a book through a height. Negative work -. 1. Work done by force of gravity on an object when lifted. 2. Work done by friction when we walk. Zero work -. WebWork is zero if applied force is zero (W=0 if F=0): If a block is moving on a smooth horizontal surface (frictionless), no work will be done. Note that the block may have large displacement but no work gets done. Work is …
WebJul 19, 2016 · Another example of zero work done in physics are: Speaking about electrostatics, work done, is the product of charge and the potential difference. If the charge is moved along an equipotential surface, then the potential difference is known to be zero between the given two points. Hope this helps . read less. 1. Comments. WebAlso, remember for work to have occurred, the object must be displaced by the force. Otherwise, the distance, or "d", in the formula is 0 and the work will be 0. Here are some examples: If someone is pushing on a wall with all their might, but the wall doesn't move, no work has occurred. This is because the distance is zero.
Web$\begingroup$ @user258314 Amount of work a vector field does may be not only positive, but also negative. If a ball drops and falls down, the gravitational vector field performs positive work that you can get out in terms of energy. After the ball hits the ground, you can lift it up back (closing the curve), so that you now has to provide energy and the vector … Web$\begingroup$ @user258314 Amount of work a vector field does may be not only positive, but also negative.
