What is gravitational force?

Back

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

What causes objects to fall to the ground?

Back

Gravity pulls objects toward the Earth, causing them to fall.

What is mass?

Back

Mass is the amount of matter in an object, which affects how much gravitational force it has.

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.

Front

What happens to gravitational force if the mass of an object increases?

Back

If the mass of an object increases, the gravitational force it exerts also increases.

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

What is weightlessness?

Back

Weightlessness occurs when there is no net gravitational force acting on an object, often experienced in space.

What is the effect of air resistance on falling objects?

Back

Air resistance slows down the fall of objects, but gravity still pulls them down.

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 their centers.

What is the gravitational force between two bowling balls placed close together?

Back

The gravitational force is relatively small but still exists due to their mass.
