Gravitational Forces

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects with mass. It pulls objects toward each other.

Front

How does mass affect gravitational force?

Back

Gravitational force increases as the mass of the objects increases.

Front

What happens to gravitational force as distance increases?

Back

Gravitational force decreases as the distance between two objects increases.

Front

What is the relationship between gravitational force and weight?

Back

Weight is the force of gravity acting on an object. It depends on the object's mass and the gravitational pull of the planet.

Front

What is the formula for 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, and r is the distance between the centers of the two masses.

Front

What does it mean for an astronaut to be 'weightless' in space?

Back

An astronaut is considered 'weightless' because they are in free fall, experiencing no net gravitational force acting on them.

Front

What is the gravitational pull of Earth?

Back

The gravitational pull of Earth is approximately 9.81 m/s².

Front

How do planets affect gravitational force?

Back

More massive planets exert a stronger gravitational force compared to less massive planets.

Front

What is the effect of gravity on falling objects?

Back

All objects fall at the same rate in a vacuum, regardless of their mass, due to gravity.

Front

What is the significance of the gravitational constant (G)?

Back

The gravitational constant (G) is a key value in the formula for gravitational force, determining the strength of gravity between two masses.
