What is the relationship between velocity and gravity?

Answer 1

The relationship between force and acceleration mathematically is proportional, as seen in the second low of motion F = m*a. The acceleration of an object will be equal to the ratio of the net force on the object to the mass.

Answer 2

Gravitational acceleration decreases with increase in height from the surface of the earth.

At a height 'h' above the surface of earth,

g' = GM/(R+h)2

where G : universal gravitational constant M : mass of earth R : radius of earth

Answer 3

The relationship between acceleration and mass is that force = mass x acceleration. This is also known as F=ma and is derived from Newton's Second Law. This is because acceleration is directly proportional to the net force acting on a body. The acceleration of an object is also inversely proportional to the mass of that object but in free fall the acceleration is independent of the mass - on the Earth it is always

9.81ms-1.

Answer 4

Force equals mass times acceleration.

F = ma

Answer 5

While falling towards the earth

1) v = u + gt

2) v^2 = u^2 + 2gh

While working against the gravity

1) v = u - gt

2) v^2 = u^2 - 2gh

Answer 6

Nothing
