Galileo Physics Gravity Lesson 1 Difference Between Mass

Galileo Physics: Gravity Lesson #1 Difference Between Mass and Weight

Mass of objects and the relative distance from one another creates the effect of gravity. MASS 5. 98 x 10^24 Kg 2 x 10^30 Kg DISTANCE 1. 50 x 10^8 Meters 9. 3 x 10^7 Miles Astronomical Unit

First Ingredient of gravity is mass What is mass? How do you find the mass of a person? What would a scale register if a person step on a scale in the International Space Station? What does an ordinary bathroom scale measure?

So Bathroom scales measure weight! How is weight different than mass? Would the bathroom scale register your weight the same if you were using it on the moon? Would your mass be the same if you were standing on the moon? How is the Moon and Earth different? Definition: Mass is the amount of matter or substance.

If mass is the amount of matter then what is weight? If your weight is different when you are on two different planets; then what is an essential component in calculating weight? The total mass of the specific planet you are standing on and your own mass will determine your weight!! Remember Gravity is determined by Mass A person with the mass of 100 Kg. On Earth will weigh 100 Kg. On Earth, because scientist have denoted Earth as having a gravity of 1.

A person with the mass of 100 Kg. On Earth will weigh 100 Kg. On Earth, because scientist have denoted Earth as having a gravity of 1. Calculate your weight on other planets The gravity’s of other planet are in relation to Earth’s gravity. Take your weight 120 lbs x Planet index______= weight on that planet. Example 120 lbs x 2. 36 Jupiter’s gravity = 283 lbs. Earth Jupiter Planet Gravity Earth 1 Moon 0. 17 Venus 0. 90 Mercury 0. 38 Mars 0. 38 Jupiter 2. 36 Saturn 0. 92 Uranus 0. 89 Neptune 1. 13 Pluto 0. 07

Mass is the amount of matter an object has whether it is as small as an Atom or has large as a planet. Weight is a relationship between the gravitational pull between objects of mass. Example: the effect a bathroom scale shows when a person step on it. The mass of the person is being pulled towards the center of the Earth and exerting a force upon the scale.
