For the horizontal axis, we will plot t 2 instead of just time since the distance should be proportional to time squared. Notice that a linear function does indeed fit this data quite nicely.

The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an ...

Forces may change the shape of an object. An elastic object, such as a spring, stores elastic potential energy when stretched or squashed. The extension of an elastic object is directly ...
