Transcript: Gravity Solid- Bonds are very strong. Particles are kept in place and Vibrate. Liquid- Bonds start to weaken allowing the particles to slide past each other. Gas- Bonds dissappear, and the particles fly everywere. After pressure drops CO2 will try to escape the air. If there was no gravity water would not fall and there would be no pressure. without gravity Asphalt would not be able to set. Earth VS. Outer Space Earth has gravity. Outer Space doesn't. therefor gravity hold's us onto the ground, and in Outer Space you would float. Space Flight Exeriments- There is a Weightless Flight Program that teachers are allowed to do as a hands-on-activity. The program was developed in cooperation with the Zero Gravity Corporation (ZERO-G), Ft. Lauderdale, Fla., a company that specializes in bringing the exhilaration of weightlessness to the general public. As part of the program, practicing classroom middle school teachers and future middle school teachers have the opportunity to participate in hands-on science workshops, and perform and experiment in a parabolic or "zero-gravity" aircraft flight that creates temporary weightlessness comparable to what humans would experience during space travel to the moon or Mars. It also mimics how astronauts train for space flights. Here is a story i found on Space Flight Experiment's- Plasma- A highly ionized gas, usually at a high temperatures that conduct electricity and is effected by a magnetic field.

Transcript: How fast does Gravity pull you down??? Mass is the amount of matter something contains, and weight is the measurement of the pull of gravity on an object. Weight is how you pull on gravity. Mass is ur size. And lastly Newtons is what unit its in. Mars: 45.24 lbs -An interaction which tends to change the motion of an object. Describing mass, weight, and Newtons to a five year old. Worked out Problem If you are a 125 pounds on earth, you will be 275.5778277311 in Kilograms. The force that attracts a body toward the center of the earth, or toward any other physical body having mass. Fun facts about gravity: The equation of force: F=MA Force= ma 180x5=900 Take things with different weight and sizes and drop them from a certian point. Law of Falling bodies: Force= 900 Newtons To leave Earth’s gravitational pull behind, an object must travel 7 miles a second. According to scientists, people in space can lose up to 1% of their bone mass. Weight on different planets A stone who's weight is twice as much will fall faster than a smaller stone because of air resistance. Moon: 19.92lbs What is the mass of an object on earth? Graphs Mass=180lbs W=MG (Weight = Mass x Gravity What are the units for weight? He figured out this law when he dropped two balls off of the Leaning tower of Pisa. Gravity Presentation The SI unit for weight is Newtons. Acceleration vs. Time- It would be a straight horizontal line. How are weight and mass different? What is Gravity?? lab Acceleration= 5mph The speed of of gravity is 9.8 m/s Tommy weighed 180lbs and was accelerating at a speed of 5 miles p/h down a hill. What was the force when he hit the tree at the bottom of the hill. Velocity vs. Time- It would look like a diagnol line on the graph. What is force??? Distance vs. Time- It would be exponential. It would be a curve. Difference between mass, weight, and newtons: Newton is a unit in which we measure force, mass is the amount of matter something contains, and weight is the measure of pull on gravity. Examples that show the theory is true: Earth: 120lb (force=mass x acceleration) Sun: 3248.64 bs Formula for weight:

Transcript: The gravity on Saturn is slightly more than on the Earth. If you weigh 100 pounds on Earth you would weigh 106.4 pounds on Saturn. Sources Gravity on Jupiter On Venus it would be closer to the same but still not the same as the Earth. If you went to Venus you would be 90.7 pound, that's if you weighed 100 pounds on Earth. Gravity on Uranus Many people think weight and mass are the same thing, but they aren't. Mass is the measure of how much matter is in an object. Weight is how much an object weighs. Plus mass is measured in Kilograms and weight in pounds. Gravity on Mercury What is Gravity Gravity on the Moon The gravity on Jupiter is much greater than the Earth. It has greater gravity because it is larger than the Earth, therefor has more gravitational pull. If you weigh 100 pounds on Earth you would weigh 236.4 pounds on Jupiter and you would probably die because the gravity is too strong. If two objects fall from the same height in a vacuums, they fall at the same rate and land at the same time even if they are different masses. This happens because the small one has less air resistance than the object with more mass. So they will end up landing at the same time. Gravity is the force that an objects exert on each other because of their masses. Acceleration Due to Gravity Gravity on Mars Examples of Gravity Gravity Presentation If you went to mars the gravity is less than in the Earth. If you weighed 100 pounds on Earth then you would weigh 37.7 pounds. Gravity on Saturn Weight and Mass The gravity on Neptune is greater than on Earth. If you weigh 100 pounds on Earth you would weigh 112.5 pounds on Neptune. Gravity on Uranus is less than the Earth. If you weigh 100 pounds on Earth then you would weigh 88.9 pounds on Uranus. But your mass would not change while on any of these planets. Gravity on Neptune The gravity on Mercury is less that the Earth has because Mercury is smaller than the Earth. On Earth if you weigh 100 pounds then you would weigh 37.8 pounds on Mercury. Gravity is all around us. Everything has gravity in the Earth's atmosphere. This makes everything an example of gravity. Gravity on Venus Gravity on the Moon is still less than the gravity on Earth. If you weighed 100 pounds on Earth then you would weigh 16.6 pounds.
