what is gravitation ?
what are laws of gravitation​

Answer 1

Here is your Answer

1. Motion, in physics, change with time of the position or orientation of a body. Motion along a line or a curve is called translation. ... In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).
2. Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.
3. 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.
4. Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Answer 2

Explanation:

1 . The continuous displacement of an object is called motion .

2 . ( a ) An object continues to remain at rest unless an external unbalanced force acts on it .

( b ) the rate of change of momentem is proportional to the applied force and the change of momentum occurs in the direction of the force .

( c ) every action force has an equal and opposite reaction force which acts simultaneously.

3 . the force exerted by earth to pull or push object towards it , this force is called gravitation force .
