A pulley system has an mechanical advantage of 10. If a mover used this pulley to lift a piano with a force of 1500 N a distance of 4 m, how much force must the mover use?

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
