Q.1. When is work done negative?Ans. Work done is negative when the displacement caused is in the direction opposite to the direction of the force.Q.2. What is work in Physics?Ans. Work is the product of force and displacement in the direction of the force....
呢个呢就睇下个object系有冇friction的面用行motion啦... 当佢no friction呢..佢以constant v(6ms^-1)行呢..就冇work done..因为佢个velocity不变..除非你话由0ms^-1计起..咁佢就有work done..(同6加到10一样) 当佢有 friction呢..but佢又以constant v(6ms^-1)行呢..就有work d...
