PROBLEMS sec. 13-2 Newton's Law of Gravitation •1 A mass M is split into two parts, m and M – m, which are then separated by a certain distance. What ratio m/M maximizes the magnitude of the gravitational force between the parts? Answer: •2 Moon effect.Some people believe that the Moon controls their activities. If the Moon moves from being directly on the opposite side of …

m1 to m2, s1 points in the same direction and sense as s3 from m2 to m3, and s2 points back from m3 to m1.Therefore, we can write s1 = ‚s3; s2 = ¡(1+‚)s3; (7) where ‚ is a positive scalar. Expressing everything in the equations of motion in terms of s3 and lambda, one obtains after some algebra (see Hestenes 1987 for details) a flfth degree polynomial in ‚ with one single …

Chapter 4 Oscillatory Motion

Oscillatory Motion 4.1 The Important Stuff 4.1.1 Simple Harmonic Motion In this chapter we consider systems which have a motion which repeats itself in time, that is, it is periodic. In particular we look at systems which have some coordinate (say, x) which has a sinusoidal dependence on time. A graph of x vs. t for this kind of motion is shown in

• Repetitive motion through a central equilibrium point. • Symmetry of maximum displacement. • Period of each cycle is constant. • Force causing the motion is directed toward the equilibrium point (minus sign). • F directly proportional to the displacement from equilibrium. Acceleration = - ω2 x Displacement

This speed of 4 m/s is the initial speed for the oscillatory motion. Since the spring obeys Hooke’s 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= 0 at t= 0 ...

Characteristics of periodic motion • The amplitude, A, is the maximum magnitude of displacement from equilibrium. • The period, T, is the time for one cycle. • The frequency, f, is the number of cycles per unit time. • The angular frequency, , is 2π times the frequency: = 2πf. • The frequency and period are reciprocals of each other:

motion of a simple pendulum is an example of a periodic or an oscillatory motion. The pendulum is said to have completed one oscillation when its bob, starting from its mean position O, moves To set the pendulum in motion, gently hold the bob and move it slightly to one side.
