This lesson covers speed and the distance-time-speed formula, the difference between scalars and vectors, average versus instantaneous speed, acceleration in metres per second squared, and how to read ...

A horizontal line means the object is moving at a constant speed. The gradient of the line = the rate of change of speed. The steeper the line, the greater the increase in speed. The area under the ...
