Gravitation and Gravity Quiz

Study Notes

Gravity is a fundamental force that attracts two bodies towards each other.
It is responsible for keeping planets in orbit around stars and influencing the motion of celestial bodies.

Gravitation refers to the natural phenomenon where two masses attract each other.
It is the reason for the orbits of planets and the falling of objects toward Earth.

The force of gravity is calculated using Isaac Newton's Universal Law of Gravitation, which states that every mass attracts every other mass 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.
The formula is given by: ( F = G \frac{m_1 \times m_2}{r^2} ), where ( F ) is the gravitational force, ( G ) is the gravitational constant, ( m_1 ) and ( m_2 ) are the two masses, and ( r ) is the distance between the centers of the two masses.

Acceleration due to gravity is the acceleration experienced by an object because of Earth's gravitational pull.
It is denoted by the letter "g."
The standard value of acceleration due to gravity at Earth's surface is approximately ( 9.81 , m/s^2 ).

The phenomenon of attraction between any two bodies in the universe is simply called "gravitation."
This universal law applies to all matter, no matter how large or small.

The force of attraction exerted by Earth on a body is referred to as "weight."
It is calculated based on the mass of the object and the acceleration due to gravity, using the formula: ( W = m \times g ).
