Question

Why is gravity a force?

Answer 1

Gravity: Gravity is the force that pulls items toward the center of a planet or other entity.

Force: A force is an external agent capable of altering a body's condition of rest or motion.

1. Because it works between any two masses anywhere in the universe, gravity is called a universal force.
2. The Sun and the Moon, for example, have a gravitational attraction.
3. The solar system was formed by the gravitational attraction of dust and gas particles in space.
4. If $m_1$ and $m_2$ are the masses of two bodies, $r$ is the distance between them and $G$ is the universal gravitation constant, then gravitational force is given as $F=G\frac{m_1{m}_2}{r^2}$.
5. From this equation, we can see that gravitational force is directly proportional to the mass of the bodies and inversely proportional to the distance between them.

Thus, gravity is a force.
