Question
- A. Ep = m x g x h
- B. Ep = m + g + h
- C. Ep = m / g / h
- D. Ep = m - g - h
Answer
Ep = m x g x h
Explanation
The equation Ep = m x g x h calculates gravitational potential energy, where m is mass, g is gravitational field strength, and h is height.
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.
