Will mark ! an object’s or weight) will remain constant throughout the universe, but its or weight) can change from planet to planet. if you increase the mass of a planet, what happens to its gravity? (strength of gravity increases or strength of gravity decreases or strength of gravity stops completely) if the gravity on a planet decreases, what happens to the weight of an object on that planet? (weight increases or weight decreases or weight stays the same)

The acceleration due to gravity at the surface of a planet depends on the planet's mass and size; therefore other planets will have accelerations due to gravity different from 9.8 m/s2. imagine an astronaut stands on an alien planet, which has no atmosphere, and throws a rock with a speed of 7.45 m/s in the horizontal direction, releasing it at a height of 1.40 m above the surface of the planet. the rock hits the surface a horizontal distance of 8.90 m from the astronaut. find the magnitude of the acceleration due to gravity on this alien planet.

Fast ! a new solar system with two planets of equal mass - planet x and planet y - is discovered. planet x is closest to the sun. what is the sun's gravitational pull on planet y as compared with planet x? a. because planet y is farther from the sun, the sun's gravitational pull on planet y is less than the sun's gravitational pull on planet x. b. the sun's gravity repels planet y with more force than it repels planet x, which is why planet y is farther away. c. because planet y is farther from the sun, the sun's gravitational pull on planet y is more than the sun's gravitational pull on planet x. d. the sun's gravitational pull on planet y is equal to its gravitational pull on planet x because distance does not affect the sun's gravity.
