Gravity on Earth and on Mars: The acceleration due to gravity near the surface of a planet depends on the mass of the planet; larger planets impart greater acceleration than smaller ones. Mars is much smaller than Earth. A rock is dropped from the top of a cliff on each planet. Give its location as the distance down from the top of the cliff.

a. On the same coordinate axes, make a graph of distance down for each of the rocks.

b. On the same coordinate axes, make a graph of velocity for each of the rocks.
