7.9B Gravity and Motion in the Solar System Flashcard

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 factors affect the gravitational force between two objects?

Back

The gravitational force depends on the mass of the objects and the distance between them.

Front

How does mass affect gravitational force?

Back

Greater mass results in a stronger gravitational force between two objects.

Front

How does distance affect gravitational force?

Back

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

Front

What happens to an object's orbit if the gravitational force increases?

Back

If the gravitational force increases, the object's orbit could become smaller.

Front

What is inertia in the context of motion?

Back

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

Front

How do inertia and gravity work together in orbits?

Back

Inertia keeps an object moving in a straight line, while gravity pulls it towards the center of the larger body, creating an orbit.

Front

What is an asteroid's orbit?

Back

An asteroid's orbit is the path it takes as it moves around a celestial body, like the sun.

Front

What happens to an asteroid's orbit when it moves away from the sun?

Back

The asteroid's orbit would slow down and have a greater path.

Front

What is the relationship between mass and distance in governing orbits?

Back

Mass and distance work together to determine the strength of gravitational attraction and the shape of orbits.
