Energy from moving parts or machines
WebA machine cannot increase the amount of energy you put into it. So, why is a simple machine useful? Although it cannot change the amount of work you do, a simple … Webfriction at the moving parts. The output work is always less than the input work because some input work is used to overcome friction. Therefore, efficiency is always less than 100%. All machines make work easier, but they don’t increase the …
