Questions & Step-by-Step Solutions

What is the gravitational potential energy of two masses m1 and m2 separated by a distance r?
  • Step 1: Identify the two masses involved in the problem, which are m1 and m2.
  • Step 2: Determine the distance between the two masses, which is represented by r.
  • Step 3: Understand that G is a constant called the gravitational constant, which is approximately 6.674 × 10^-11 N(m/kg)^2.
  • Step 4: Use the formula for gravitational potential energy, which is U = -G * (m1 * m2) / r.
  • Step 5: Plug in the values of m1, m2, r, and G into the formula to calculate the gravitational potential energy U.
