What is an example of electrical energy to mechanical energy?
What is an example of electrical energy to mechanical energy? Many devices are used to convert mechanical energy to or from other forms of energy, e.g. an electric motor converts electrical energy to mechanical energy, an electric generator converts mechanical energy into electrical energy and a heat engine converts heat energy to mechanical energy.

What is the normal force between the two blocks?
What is the normal force between the two blocks? In other words, acceleration of each of the block is “gsinθ”. As such, the blocks move with equal acceleration and hence there is no normal force between the surfaces of the two blocks. What if there was no normal force? The normal force is very important […]
