Gravity Quiz

Gravitation Overview

• Gravitation is a universal force of attraction acting between all masses in the universe.
• It is one of the four fundamental forces, alongside electromagnetism, the weak nuclear force, and the strong nuclear force.

Factors Affecting Gravitation

• Gravitation depends on two main factors: the masses of the objects involved and the distance between them.
• The greater the mass of the objects, the stronger the gravitational pull.
• As the distance between objects increases, the gravitational force decreases.

Descent of Objects

• A body falls downwards when dropped due to the force of gravity acting on it, pulling it towards the Earth’s center.
• The acceleration of falling objects is constant at approximately 9.81 m/s² near the Earth's surface.

Movement of Thrown Objects

• When a body is thrown upwards, it initially rises against the force of gravity until it loses momentum and starts descending.
• The upward motion decelerates until the object reaches its peak height, where the velocity becomes zero before falling back down.

Proportionality of Gravitational Force

• The force of gravitation is directly proportional to the product of the masses of the two objects.
• This relationship is expressed by the equation: F = G(m1*m2)/r², where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.
