This first graph shows Distance versus Time for free falling objects on 3 different planets- Earth, Jupiter, and Pluto. Each line represents the velocity on each planet. The lines represent that the acceleration and velocity are greater on Jupiter than on Earth, and both are greater than on Pluto. Jupiter has a much greater velocity than Earth, and Earth has a greater velocity than Pluto, however it is only a bit greater, not as much as Jupiter.
This other graph shows Final Velocity versus Time for falling objects on 3 different planets- Jupiter, Earth, and Pluto. The lines show that the objects are falling at a constant rate. They show that Jupiter has the highest gravitational pull, Earth has a middle pull, and that Pluto barely makes it on the graph with it's gravitational pull.

ReplyDeleteThe straight lines on Vf vs time don't say that it is a constant rate. In fact, rate = velocity and that is clearly changing for each planet. What do those straight lines me about the motion of these objects in freefall?

They tell you that the longer they fall, the higher the velocity is, although it increases at the same number.
