GPE = m × g × h

Gravitational potential energy is the energy an object possesses due to its height above the ground. The gravitational potential energy (GPE) of an object is given by the equation: GPE = m × g × h Gravitational

Then, calculate the efficiency:

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. calculate the efficiency:

W = F × s

Then, calculate the efficiency:
