A machine lifts a 100 kg load to a height of 5 m in 10 seconds. If the machine requires an input energy of 5000 J, calculate its efficiency.

Energy is the ability to do work. There are two main types of energy: kinetic energy and potential energy. A machine lifts a 100 kg load to

Potential energy is the energy an object possesses due to its position or configuration. There are two main types of potential energy: gravitational potential energy and elastic potential energy. A machine lifts a 100 kg load to

W = F × s = 20 N × 3 m = 60 J

Efficiency is a measure of how much of the input energy is converted into useful work. It is calculated using the equation: A machine lifts a 100 kg load to
