GPE = m × g × h = 10 kg × 9.8 m/s^2 × 4 m = 392 J

Efficiency is a measure of how much of the input energy is converted into useful work. It is calculated using the equation:

A 5 kg object is lifted to a height of 2 m above the ground. Calculate its gravitational potential energy. GPE = m × g × h = 10 kg × 9

KE = ½ × m × v^2

A 2 kg car is moving at a velocity of 4 m/s. Calculate its kinetic energy. KE = ½ × m × v^2 A

Solution:

A 5 kg object is moving at a velocity of 2 m/s. Calculate its kinetic energy. Calculate its kinetic energy

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.
