Distance-time graphs show how the distance travelled by a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, going back to the ...

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.

Newton's Second Law states that force equals mass times acceleration. This can be investigated using a set-up like this one. You can use this set-up to investigate how changing two separate factors, ...
