On Earth, a person has a weight of 520 N. What weight would the person have on Mars? Theradius of Mars is 53% of the radius of Earth, and its mass is 11% of the mass of Earth.
the ship was 1000 kgm when it left earth. How much doesi t weigh in N and kgf if it lands on solid ground in another planet with g = 20 m/s2?
The planet Jupiter is more than 300 times as massive as Earth, so it might seem that a body on the surface of Jupiter would weigh 300 times as much as on Earth. But it so happens that a body would scarcely weigh 3 times as much on the surface of Jupiter as it would on the surface of Earth. Can you think of an explanation for why this is so? (Hint: Let the terms in the equation for gravitational force guide your thinking.)

- An astronaut is in space with a baseball and a bowling ball. The astronaut gives both objects an equal push in the same direction. Does the baseball have the same inertia as the bowling ball? Why? Does the baseball have the same acceleration as the bowling ball from the push? Why? If both balls are traveling at the same speed, does the baseball have the same momentum as the bowling ball?arrow_forwardIn the law of universal gravitation, Newton assumed that the force was proportional to the product of the two masses (m1m2) . While all scientific conjectures must be experimentally verified, can you provided arguments as to why this must be? (You may wish to consider simple examples in which any other form would lead to contradictory results.)arrow_forwardThe mass of Jupiter is 314 times that of Earth and the diameter of Jupiter is 11.35 times that of the Earth.

You might quickly infer that an object on the surface of Jupiter would weigh 300 times more than on the surface of the Earth. For instance, you might expect a person who weighs 500 N on Earth would weigh 150,000 N on the surface of Jupiter. Yet this is not the case. In fact, a 500-N person on Earth weighs about 1500 N on the surface of Jupiter. Explain how this can be.arrow_forward
- Since all objects are “weightless” in orbit, how is it possible for anorbiting astronaut to tell if one object has more mass than anotherobject? Explain.arrow_forwardYou are to solve this problem using only the tools of dimensional analysis. You are not expected to know anything about gravitation. Do not use any equations about gravity! They won't help you, anyway. Use only dimensional analysis. This problem involves estimation, but do not guess. Neatly work out your solution using dimensional analysis. You will be asked to upload your work in the next problem. Newton's Law of Gravitation tells us that any two objects attract each other by pulling each other with a gravitational force. In principle, any two objects far out in space (far from other objects) should attract each other and come together using only their gravitational attraction, but how long would this take? Newton's gravitational constant is G = 6.67 x 10-11 (m2)/(s2 kg) That says G = 6.67 x 1011 (m2)/(s² kg) (Notice that the denominator is "seconds squared" times "kg") Imagine two astronauts far out in space, very far from other objects (the picture above shows the Earth in the…arrow_forwardThis morning a Houston-based startup company named Axiom-1 Space launched an all-private astronaut crew on a SpaceX Falcon-9 Rocket to fly to the International Space Station (ISS).

(Round answer to the nearest tenth) c) Determine the gravitational force of attraction between the earth and the ISS given earth's mass is 6× 10^24 kg . d) Determine the tangential velocity of the ISS.

- You may have an image of Sir Isaac Newton sitting under a tree and after being hit on the head by an apple he suddenly "discovered" the Law of Universal Gravitation. In fact, the theory was a result of years’ worth of research, which in turn was based on centuries of accumulated knowledge. He is credited with determining that the following relationship is universal. The gravitational attraction between two objects varies jointly with their masses (m1 and m2) and inversely with the square of the distance (d) between them. By what percent does the force of gravitational attraction change if one mass is increased by 20%, the other mass decreased by 20%, and the separation is reduced by 25%?arrow_forwardWhen you travel to another part of the solar system (Jupiter, Mars, etc) what changes, your mass or your weight?
