Energy is the ability to do work. There are two main types of energy: kinetic energy and potential energy.

KE = ½ × m × v^2 = ½ × 5 kg × (2 m/s)^2 = 10 J Energy is the ability to do work

Then, calculate the efficiency:

where m is the mass of the object, g is the acceleration due to gravity (approximately 9.8 m/s^2), and h is the height of the object above the ground. Energy is the ability to do work
