1 Kepler’s Third Law - University of Massachusetts Amherst


Kepler’s Third Law says P2 = a3: After applying Newtons Laws of Motion and Newtons Law of Gravity we nd that Kepler’s Third Law takes a more general form: P2 = " 4ˇ2 G(m1 +m2) # a3 in MKS units where m1 and m2 are the masses of the two bodies. Let’s assume that one body, m1 say, is always much larger than the other one. Then m1 ...

Exercises on Oscillations and Waves Exercise 1 - CPP


f = 4 m=s This speed of 4 m/s is the initial speed for the oscillatory motion. Since the spring obeys Hookes law, the motion is one of simple harmonic (i.e. sinusoidal) withq != k=m= q 16=4 = 2 s 1. The general expression for simple harmonic motion is: x(t) = x 0cos(!t) + v 0! sin(!t) (10) For our example, x 0 = 0 since the blocks are at x ...
