Gravity and Planetary Motion

Front

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

Back

Gravity increases.

Front

Which planet has the greatest gravitational attraction with the sun?

Back

Mercury.

Front

Which planet has the lowest gravity?

Back

Planet B.

Front

What happens to gravity as the distance between interacting objects increases?

Back

Gravity decreases.

Front

If two planets have the same mass, which one would have a lower orbital speed?

Back

The planet that is farther from the sun.

Front

Define gravity.

Back

Gravity is the force that attracts two bodies towards each other, proportional to their masses and inversely proportional to the square of the distance between them.

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 orbital speed?

Back

Orbital speed is the speed at which an object must travel to maintain a stable orbit around a planet or star.

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 attraction?

Back

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