Question
A 5 kg object is lifted to a height of 10 m. Calculate the gravitational potential energy gained by the object.
Answer
490 J
Explanation
This answer is strong as it uses the gravitational potential energy formula, Ep = m × g × h, where m is mass, g is gravitational field strength, and h is height. The question tests the ability to apply the formula to calculate energy changes.
Common mistake
Common Mistake in Energy Calculation
Students often confuse the work done by forces with the energy stored in a system, leading to incorrect calculations.
Ensure to clearly differentiate between work done and energy changes in a system. Remember that work done by forces results in energy transfer, which can change the energy stores in the system.
