Can someone please explain it to me ASAP?!!!! This is universal law of gravity
According to Newton, two objects attracted by gravity actually both orbit around their common center of mass. That means:
a
the Sun is not orbiting because it's too big and too massive compared with Earth
b
the Sun is not orbiting because it's too far from Earth
c
the Sun is not orbiting because stars do not orbit
d
the Sun is orbiting but we can't clearly see it because it's too big and too massive compared with Earth
Compare the gravitational attraction between objects on earth and interaction of celestial bodies in space. Which gravitational force is almost negligible? Why?
Discuss why the study of a gravitational field is important.

- The Universal Law of Gravity states that the force of gravity acts between all objects. Nonetheless, you never feel that the fridge in your kitchen pulls you toward it. Why?arrow_forwardAccording to Newton's Law of Gravity, if you triple the distance between two objects, then the gravitational force between them will go (up or down)? by a factor of (six,three,two or nine)?arrow_forwardNewton tells us that gravitational force acts on all bodies in proportion to their masses. Why, then, doesn’t a heavy body fall faster than a light body?arrow_forward
- If you were on an alien planet, where multiple sources of gravity were affecting you, would the stronger gravity take precedence or would they cancel one another out? And why?arrow_forwardNewton viewed the curving of the path of a planet as being caused by a force acting upon the planet. How did Einstein view the curved path of a planet?arrow_forwardWhy, if the sun is so much more massive than the moon, isn’t it responsible for the Tides?

- Name the absolute unit and gravitational unit of force.arrow_forwardCalculate the force of gravity between a newborn baby (mass = 3 kg) and the planet Mars (mass = 6.4 × 1023 kg) when Mars is at its closest to Earth (distance = 5.6 × 1010 m).arrow_forwardLet's say we were to measure the force of gravity between two objects. Next we increase the mass of one of the objects by a factor of 6 (aka it is 6 times more massive) and decrease the mass of the other by a factor of 2 (aka it is 1/2 the original mass). How does the force of gravity in this new case compare to the original case? (aka how many times larger (value greater than 1) or smaller (value smaller than 1) is the force of gravity in the new case?arrow_forward
- How is Newton's first law a special case of the second law?arrow_forwardI have been struggling to solve this question. Could anyone help me? According to Newton's Law of gravitation, if you increase the distance between two masses by a factor of 5, how does the gravitational force between them change?arrow_forwardPlease prove the relationship between gravity and universal gravitation on Earth , and use the expression to explain in detail .
