Once I have the total force acting on mass 2, I can use the momentum principle to find how its momentum changes. With the momentum of mass 2, I can find out where it is after some short time interval.

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

A basic pendulum is a mass at the end of a string that swings back and forth. It seems simple, and it appears in most introductory physics textbooks. But it's not a trivial problem to solve for ...

That's a pendulum in motion! On today's MOSI Monday, we're looking at pendulum and angular momentum! Ian Reed, manager of academic & youth programs at MOSI, shows us how gravity and energy work ...
