mass is very obvious when comparing the resistance of two bodies to a change in their motion. The greater the
mass of a body, the less its motion will be influenced by outside forces. Which is easier to stop, a truck going
50 mph, or a baseball moving at the same speed?
The terms mass and weight are often used interchangeably. Although, they actually refer to different
properties. Mass is a measure of the amount of matter in an object, and is independent of the position or
surroundings of the object, whereas weight is defined as the force exerted on an object by the pull of gravity.
The mass of an object is constant, but its weight varies with its location. Your weight would change drastically
if you went to the moon because the moon, being smaller than the Earth, exerts only 1/6 the attraction due to
its gravity that the Earth does. If you weighed 150 lb on Earth you would weigh only 25 lbs of the moon.
