Acamera weighing 21 n falls from a small drone hovering 28 m overhead and enters free fall. what is the gravitational potential energy change (in j) of the camera from the drone to the ground if you take the following reference points?

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
