Question
What is the equation used to calculate gravitational potential energy gained by an object raised above ground level? Define each variable in the equation.
Answer
The equation is Ep = m x g x h, where Ep is the gravitational potential energy in joules, m is the mass of the object in kilograms, g is the gravitational field strength in newtons per kilogram, and h is the height in metres.
Explanation
This question tests the student's understanding of the gravitational potential energy equation and the definitions of its variables, which are fundamental concepts in physics.
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.
