In the following video Paul Andersen explains how the linear momentum is equal to the product of the mass of an object and the velocity of the center of mass. He uses video analysis software to calculate the velocity of an object and...

In the following video Paul Andersen explains how the center of mass of an object represents the average position of matter in an object. The center of mass of a system is a combination of all the objects within the system. As long as no...

An introduction to the center of mass. [9:35]

Learn how physicists define the term, center of gravity, and how it differs from center of mass. [1:13]

In the following video Paul Andersen explains how Newton's Second Law applies when a net force acts on a body. The net force vector and the acceleration vector will act in the same direction. If an object acts on another object in a...

COLLISIONS! A big part of physics is understanding collisions and how they're not all the same. Mass, momentum, and many other things dictate how collisions can be unique. In this video episode of Crash Course Physics, Shini sits down to...

NBC's Lester Holt describes what torque is and how the application of this force on an object causes it to spin. Professors Tony Schmitz of the University of Florida and Jim Gates of the University of Maryland explain that battles on the...

This video lesson from Khan Academy covers the center of mass for student who are studying high school physics. Sal gives a conceptual understanding of what center of mass means.

This lesson introduces the concept of center of mass.
