... only to stop it from rolling, or to divert it in another direction. Contrary to Aristotle’s arguments, the motion of a moving ball at uniform velocity (constant speed in a straight line) is quite “natural.” It needs no explanation. What must be explained is why it ever changes that motion. And this ...

... placed on a spring’s end and displaced 2.0 m to the right. The spring force F vs. its displacement x from equilibrium is shown in the graph. (b) Find the spring constant of the spring. SOLUTION: Use Hooke’s law: F = -kx. Pick any F and any x. Use k = -F / x. Thus k = -(-5.0 N) / 1.0 m = 5.0 Nm-1. ...
