Why Weighted Balls Work.
... For example, a pitcher can have a hypermobile elbow joint (e.g. a double-jointed elbow), that causes increased laxity around the elbow. Unlike laxity in the shoulders, laxity in the elbow is a very bad thing! Pitchers want a very stable elbow. The UCL’s entire function is to keep the elbow together ...

... We now apply the formalism/methodology that we have developed in the previous lectures on low-order multipole EM radiation {E(1), M(1), E(2), M(2)} to an arbitrary configuration of electric charges and currents, only restricting these to be localized charge and current distributions, contained withi ...

... A trained sea lion slides from rest with constant acceleration down a 3.0-mlong ramp into a pool of water. If the ramp is inclined at an angle of 23 above the horizontal and the coefficient of kinetic friction between the sea lion and the ramp is 0.26, how long does it take for the sea lion to make ...

Circular Motion and Gravitation Newton*s Law of Gravitation
... The gravitational field strength g is the force per unit mass acting on m due to the presence of M. Thus g=F/m gravitational field strength The units are newtons per kilogram (N kg -1). Note that from Newton’s second law, F = ma, we see that a N kg -1 is also a m s -2, the units for acceleration. ...
