Question

Why do all objects have a tendency to fall towards the Earth when thrown up?

Answer 1

Gravitational force:

1. According to Newton’s universal law of gravitation, the force of attraction between any two bodies is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them.
2. Mathematically, it is represented as,

$F=\frac{G{m}_1{m}_2}{r^2}$

where, $F$ is the gravitational force, $m_1$ and $m_2$ are the masses of the bodies respectively, $G=6.67x{10}^{-11}{\mathrm{Nm}}^2{\mathrm{kg}}^{-2}$ is the gravitational constant and $r$ is the distance between the centers of two bodies.

Explanation:

1. All objects have a tendency to fall towards the Earth when thrown up due to the influence of gravity. The gravitational force acts upon the body and it tends to fall towards the Earth.
2. Each body in the universe is attracted to each other and this force is called gravitational force.
3. The effect of gravitational force is under the gravitational acceleration that acts on the free-falling object. Hence, all objects have a tendency to fall towards the earth when thrown u

Thus, the Earth's gravitational pull is very strong. All things on Earth are drawn to the center of the planet by this attraction. Because of this, everything on Earth has a tendency to fall toward its center.
