What is gravitational force?

Back

Gravitational force is the attraction between two objects with mass, which is proportional to the masses of the objects and inversely proportional to the square of the distance between them.

How does mass affect gravitational force?

Back

Gravitational force is stronger on more massive objects. The greater the mass of an object, the stronger its gravitational pull.

What is the relationship between distance and gravitational force?

Back

Gravitational force decreases as the distance between two objects increases. It follows an inverse square law.

What is the formula for calculating gravitational force?

Back

The formula is F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.

What is weight?

Back

Weight is the force of gravity acting on an object, calculated as the mass of the object multiplied by the acceleration due to gravity (W = m * g).

What is the gravitational constant (G)?

Back

The gravitational constant (G) is a key quantity in Newton's law of universal gravitation, approximately equal to 6.674 × 10^-11 N(m/kg)^2.

What happens to gravitational force when two objects are identical in mass?

Back

Gravitational forces are strongest between objects with identical masses, as they exert equal attraction on each other.

What is the effect of Earth's gravity on objects?

Back

Earth's gravity pulls objects towards its center, giving them weight and causing them to fall when dropped.
