Reading motion from position-time graphs

Determine whether a cart is speeding up, slowing down, or moving at constant velocity from an x-t graph, and explain the reasoning using slope rather than height.

What you will be able to do

By the end of this lesson you can look at a position-time graph and say, with units, how the object is moving. You will treat the slope as velocity and the height as position — even when a high graph is almost flat.
