Gravity Review

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

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

Back

The gravitational force increases as the mass of an object increases.

Front

What happens to gravitational force when the distance between two objects increases?

Back

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

Front

What is the relationship between mass and gravity?

Back

More mass means more gravity; less mass means less gravity.

Front

When will the gravitational force between two objects be the least?

Back

When the masses of both objects are small and the objects are far apart.

Front

How does gravity affect weight?

Back

Weight is the force of gravity acting on an object; more gravity means more weight.

Front

What is the formula for gravitational force?

Back

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 is the gravitational pull of Earth?

Back

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

Front

How does gravity affect objects in space?

Back

Gravity keeps planets in orbit around stars and moons in orbit around planets.

Front

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.
