DIFFERENCE BETWEEN MASS AND WEIGHT If you're not really sure what are the differences between mass and weight, this section would be the best place to find out. These quantities are generally defined previously: Mass refers to the amount of matter an object contains (it is also a measure of inertia), and the weight is related to the force of gravity (i.e., the gravititaional force acting on an object). However, the quantities are related, and Newton's second law clearly shows this relationshipOn the suface of the Earth, where the acceleration due to gravity is relatively constant (about 9.8m/s squar), the weight force w on an object with a mass m is given by the following formula:
Mostly, a physical object has the same amount of matter, and so it has the same or a constant mass. But weight may be different because the weight is based on the gravity. Which means, your weight would be different on the moon than on Earth due to the difference on the gravitational pull. |
