Question: If the mass of an object is halved and the distance from the center of the Earth is doubled, what happens to the gravitational potential energy?

Options:

  1. It remains the same.
  2. It doubles.
  3. It halves.
  4. It quadruples.

Correct Answer: It halves.

Solution: 

Gravitational potential energy is directly proportional to mass and inversely proportional to distance, so it halves.

Questions & Step-by-Step Solutions

If the mass of an object is halved and the distance from the center of the Earth is doubled, what happens to the gravitational potential energy?
  • Step 1: Understand that gravitational potential energy (GPE) depends on two things: mass and distance from the center of the Earth.
  • Step 2: Remember the formula for gravitational potential energy: GPE = (mass * gravitational constant * height).
  • Step 3: If the mass is halved, it means we multiply the mass by 0.5.
  • Step 4: If the distance from the center of the Earth is doubled, it means we multiply the height by 2.
  • Step 5: When we calculate the new GPE, we have: New GPE = (0.5 * mass * gravitational constant * (2 * height)).
  • Step 6: Simplifying this gives us: New GPE = (0.5 * mass * gravitational constant * height * 2) = mass * gravitational constant * height.
  • Step 7: This shows that the new GPE is equal to the original GPE, meaning it does not change.
  • Gravitational Potential Energy – Gravitational potential energy (U) is given by the formula U = -G(m1*m2)/r, where G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers.
  • Proportional Relationships – Understanding how changes in mass and distance affect gravitational potential energy, specifically that it is directly proportional to mass and inversely proportional to distance.
