Rotational Motion - SFA Physics and Astronomy
... 1. Draw in the line of action of the force. This is a line through the force extending in both directions. 2. Locate the axis of rotation (pivot point). 3. The lever arm is the shortest distance from the axis to the line of action. ...

... begins with clouds of gas and dust measuring many lightyears in size. Such clouds can be found throughout our galactic home, the Milky Way, and for billions of years, they have acted as cosmic nurseries. In broad terms, what happens next has been known for decades: when a suitably large part of such ...

MATH 231 Kepler`s Second Law
... Theorem. Suppose that an object of mass m is moving in the plane. Let r(t) = x(t) i + y(t) j be the position vector at time t and let r(t) = ||r(t)|| and let θ(t) be the angle that r makes with the x-axis. (In other words, (r, θ) are the polar coordinates of the object). Then the angular momentum is ...
