Question

A camera weighing $10 \mathrm{N}$ falls from a small drone hovering $20 \mathrm{m}$ overhead and enters free fall. What is the gravitational potential energy change of the camera from the drone to the ground if you take a reference point of (a) the ground being zero gravitational potential energy? (b) The drone being zero gravitational potential energy? What is the gravitational potential energy of the camera (c) before it falls from the drone and (d) after the camera lands on the ground if the reference point of zero gravitational potential energy is taken to be a second person looking out of a building $30 \mathrm{m}$ from the ground?

Step 1

It is the energy an object possesses because of its position in a gravitational field. The formula for gravitational potential energy is PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height above the reference point. Show more…
