Front

Two objects have a certain gravitational force between them. What would happen if the mass of one of the objects suddenly increased?

Back

The gravitational force between the two objects would increase.

Front

Why are Earth, other solar system planets, and most planetary objects spherical?

Back

force of gravity acting evenly in all directions around the center of mass

Front

Planets are held in their orbit because of their large sizes as well as a certain force that acts over a distance. Which force is responsible for acting on the planets?

Back

gravitational force

Front

The diagram shows a satellite in orbit around Earth.
It is orbiting in the direction shown and is pulled toward Earth by gravity. What would happen if Earth’s gravity suddenly disappeared?

Back

The satellite would move into space in a straight line.

Front

The dotted lines in the picture show orbital paths of objects. Which statement is true about all of the orbits shown?

Back

The force of gravity is what holds each object in its orbit.

Front

Which of these is Newton's third law of motion?

Back

For every action there is an equal and opposite reaction.

Front

What is the first stage in the diagram shown?

Back

This stage shows a large collapsing cloud of gas and dust.
