Give one example when work done by force is zero even that displacement is not zero |
|
Answer» ong>Answer: A SIMPLE example of zero work is when you STAND holding a bag in your hands and do not move it. Your hands apply a force on the bag to balance the force of gravity exerted on it but since there is no displacement of the bag, the work done on it by you (your force) and ALSO the gravity is zero.In short: Yes, no work is done because the particles does not move, thus →s=0. Yes, you can CALCULATE the work done by each force. ... Note that because there is no displacement, the value of the applied FORCES are equal. |
