Answer:
Gravity.
the force that attracts a body towards the center of earth is called Gravity.
Explanation:
the Physics tells us that the every object in the universe attracts another object which some force of attraction and this force of attraction is known as gravitational pull .
Newton tells us that every object in this universe will be attracted by some gravitational pull exerted by our earth and this force of attraction which holds every object towards the ground is known as gravitational pull or the gravity
the scientist also tells us the formula to find out the force of gravitation
FG is the magnitude of the force of gravitational attraction between any two objects,
m1 is the mass of one object, m2 is the mass of a second object,
d is the distance between the centers of the two objects
F = Gm1m2/d^2
the some of the benefits of gravity are
- Gravity is a "constant force" which keeps things in place.
- Gravity keeps our muscles and bones, up and working.
- Gravity allows earth to retain its atmosphere.
- Gravity, being able to store its energy as "potential energy", allows us to harness it. E.g: water dams.
some disadvantages of gravity are
Disadvantages of gravity:
Earth's gravity can pull any large rocks or asteroids , which once entered into our atmosphere can produce catastrophic damage.
