Question

 1. What is the straight line motion caused by the gravitational pull of the earth?

           A. free fall motion                                  B. horizontal motion           

           C. projectile motion                           D. none of these​

Answer 1

Explanation:

Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects. You exert a gravitational force on the people around you, but that force isn't very strong, since people aren't very massive. When you look at really large masses, like the Earth and Moon, the gravitational pull becomes very impressive. The gravitational force between the Earth and the molecules of gas in the atmosphere is strong enough to hold the atmosphere close to our surface. Smaller planets, that have less mass, may not be able to hold an atmosphere.

Answer 2

Answer:

A. Free Fall Motion

Explanation:

According to module, Freefall is a natural motion occurring due to the tendency of nature to established balance to bring disturbing elements to its natural resting place. Objects move downward because gravity disturbs their motion.
