A negative gradient shows the rate of “slowing down” or deceleration. Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The gradient ...

One of the most basic things students do in a physics lab is to collect data and use that to build a model. Most of these models come in the form of a mathematical function. But here is the problem.

A horizontal line on a distance-time graph close distance-time graphA graph with distance travelled plotted on the vertical axis against time taken on the horizontal axis. shows that the object is ...
