Gravitation
This blog is about chapter gravitation.
The universal law of gravitation states that every object in the universe is attracted to every other object with a force that is inversely proportional to the square of the distance between them and directly proportional to the product of their masses.
The line connecting the centres of the two objects is where the force is felt.
Importance of the law of gravitation in general
The universal law of gravitation effectively explains a number of phenomena, including:
- the thing that keeps us attached to the ground.
2. the moon’s orbiting the earth.
3. the planets’ orbital movements around the sun.
4. the moon and sun’s influence on the tides.
Freefall
We refer to an object as being in free fall when it is only falling towards the earth due to gravity.
A body that is falling freely is said to have accelerated velocity.
Gravitational acceleration, or “g acceleration,” is what this acceleration is known as. m/s2 is the unit.
The mass of the body has no bearing on how items move when subject to the force of gravity, or “g.” Small, large, heavy, light, hollow, and solid things all fall at the same pace.
Mass and weight
Mass:- The inertia of an object is measured by its mass. It is the substance contained in it. Everywhere throughout the cosmos, it is unchanged.
Weight:- The weight of the thing is the result of the earth’s gravitational pull on it. Newton is the SI unit it uses.
W = m x g
