Question

What is gravitation ??
what is free fall ??​

Answer 1

Answer:

• Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.

• Free-fall, in mechanics, state of a body that moves freely in any manner in the presence of gravity. The planets, for example, are in free-fall in the gravitational field of the Sun. ... Gravitational forces are never uniform, and therefore only the centre of mass is in free-fall.

Answer 2

Answer:

In physics, gravitation is the force that pulls two masses toward each other. Believe it or not, every single particle of matter in the universe exerts gravitation on every other particle. The terms gravitation and gravity are often used interchangeably for the attraction between everything with energy or mass.
