### Mass Vs Weight 2

1. 1. Mass vs. Weight <ul><li>When looking at mass and weight in combination, mass is an intrinsic property of matter, whereas weight is a force that results from the action of gravity on that matter. </li></ul>
2. 2. Mass
3. 3. Mass <ul><li>Mass is scalar (a variable that only has magnitude) </li></ul>
4. 4. Mass <ul><li>Mass of an object remains the same no matter the location. This means that, unlike weight, your mass remains the same no matter how far away from the earth you are. </li></ul>
5. 5. Mass <ul><li> The measure of the amount of “stuff” contained in an object </li></ul>
6. 6. Mass <ul><li>is the quantity of matter in the thing you are studying. The metric unit of measurement of mass is the kilogram (kg), which is 1000 grams. The English unit is the slug, which is rarely used. The mass center of an object is where the balance point is. </li></ul>
7. 7. Mass <ul><li>Mass is measured by using a “balance”. In its conventional form, this class of measuring instrument compares the sample, placed in a weighing pan (weighing basin) and suspended from one end of a beam with a standard mass or combination of standard masses in a scale pan (scale basin) suspended from the other end </li></ul>
8. 8. Weight
9. 9. Weight <ul><li>Weight is a vector (has both magnitude and direction </li></ul><ul><li>When looking at the truck example above, it has a magnitude of 35 kmph while moving in a forward direction </li></ul>
10. 10. Weight <ul><li>A force, which arises when a mass is acted on by gravity. The metric unit of weight should technically be the Newton (N), which is the unit of force, but commonly it is the kilogram of mass that is used to measure weight in the metric system because gravity is about the same everywhere on the Earth. The English unit of weight is the pound (lb). </li></ul>
11. 11. Weight <ul><li>Weight can be measured by using a spring scale. A spring scale is used to measure the force acting on an object, which is the weight. </li></ul>
12. 12. Weight <ul><li>Weight of an object changes depending on its location relative to the earth. Meaning the further away from earth you are, the less you weigh. Consequently, your weight is the greatest when you are on the earths surface. </li></ul>
13. 13. Conclusion <ul><li>It is easy to confused mass and weight with each other in everyday life because the differences are not always apparent, however it is obvious when looking at these three points: </li></ul>
14. 14. 1) <ul><li>objects are compared in different gravitational fields, such as away from the Earth's surface. For example, on the surface of the Moon, gravity is only about one-sixth as strong as on the surface of the Earth. A one-kilogram mass is still a one-kilogram mass (as mass is an intrinsic property of the object) but the downwards force due to gravity is only one-sixth of what the object would experience on Earth. </li></ul>
15. 15. 2) <ul><li>masses are considered in the context of a lever, such as a cantilever structure. </li></ul>
16. 16. 3) <ul><li>locating the center of gravity of an object (although if the gravitation field is uniform, the center of gravity will coincide with the center of mass). </li></ul>
