Physics 1 - Weight

| No Comments | No TrackBacks

In everyday language, the words "mass" and "weight" are often used interchangeably. However, they are not the same thing and it is important to differentiate the two terms in physics. Mass is the amount of material an object contains, a measure of an object's inertia. Whereas, weight is the force of gravity exerted on it.

In today's free Physics 1 lecture on Weight, Professor Steve Pollock will demonstrate the difference between mass and weight and how to determine weight when mass is known. He'll discuss the impact of outer space and its low gravity on weight. The concept of weight is an important one. Distinguishing weight and mass is obviously important if you're going to use Newton's Second Law. The quantity which you're interested in when your working dynamics problems is the mass of the object.
