Common mistake
Common Mistake in Gravitational Potential Energy Calculation
Students often confuse the variables in the equation Ep = m x g x h, mistakenly using height in kilograms instead of metres.
Always ensure that height (h) is measured in metres when applying the gravitational potential energy equation.
