What is gravitational force?

Back

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

How does distance affect gravitational force?

Back

The gravitational force decreases as the distance between two objects increases.

What is the relationship between mass and gravitational force?

Back

The greater the mass of an object, the stronger the gravitational force it exerts.

What happens to your weight on different planets?

Back

Your weight changes on different planets due to varying gravitational forces, even though your mass remains the same.

What is the formula for gravitational force?

Back

The formula for gravitational force 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 the gravitational force on Earth?

Back

The gravitational force on Earth is approximately 9.8 m/s², which is the acceleration due to gravity.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as the mass of the object multiplied by the acceleration due to gravity.

How does the gravitational force between two objects change if one object's mass is doubled?

Back

If one object's mass is doubled, the gravitational force between the two objects also doubles.

What is the effect of gravity on falling objects?

Back

Gravity causes all objects to fall towards the Earth at the same rate, regardless of their mass, in the absence of air resistance.

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
