Module 7 - Gravitation

Front

What is the relationship between gravitational force and mass?

Back

Gravitational force is directly proportional to the mass of the objects involved.

Front

What is the formula to calculate gravitational force between two objects?

Back

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.

Front

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

Back

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

Front

What is the mass of Mercury?

Back

3.30 x 10^24 kg.

Front

What is the mass of the Sun?

Back

1.99 x 10^30 kg.

Front

What is the distance from Mercury to the Sun?

Back

5.79 x 10^10 m.

Front

What is the gravitational force between Mercury and the Sun?

Back

1.31 x 10^22 N.

Front

What two factors affect the magnitude of the force of gravity between two objects?

Back

Mass and distance.

Front

Does the mass of an object change as it moves further from the surface of the Earth?

Back

No, the mass of the object will not vary as it moves further from the surface of the Earth.

Front

What happens to the velocity of a satellite as its orbital radius decreases?

Back

The velocity of the satellite increases.
