Q: What is the gravitational potential energy of a mass 'm' at height 'h' above the Earth's surface?
Solution: The gravitational potential energy U at height h is given by U = mgh.
Steps: 4
Step 1: Understand that gravitational potential energy is the energy an object has due to its position above the ground.
Step 2: Identify the variables: 'm' is the mass of the object, 'g' is the acceleration due to gravity (approximately 9.81 m/s² on Earth), and 'h' is the height above the Earth's surface.
Step 3: Use the formula for gravitational potential energy, which is U = mgh.
Step 4: Plug in the values for 'm', 'g', and 'h' into the formula to calculate the gravitational potential energy.
