Gravity and Planetary Motion

Front

What are the two factors that affect the force of gravity?

Back

Mass and Distance.

Front

What happens to gravity as the mass of the interacting objects decreases?

Back

Gravity decreases.

Front

What prevents the planets from being dragged and colliding with the Sun?

Back

Inertia.

Front

When will the gravitational forces between two objects be the greatest?

Back

When the masses of both objects are large and the objects are close.

Front

What determines the gravitational force between two objects?

Back

The mass of the objects and the distance between them.

Front

Define gravity.

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does distance affect gravitational force?

Back

As the distance between two objects increases, the gravitational force between them decreases.

Front

What is the relationship between mass and gravitational force?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

What role does gravity play in planetary motion?

Back

Gravity keeps planets in orbit around the Sun and prevents them from drifting away.
