The string breaks. Describe the motion of the ball correctly.

It moves in a straight line at a tangent to the circle

It continues to move in a circular motion

Centripetal acceleration is GREATER when...

the radius of the circular motion is decreased

the radius of the circular motion is increased

What happens to the gravitational force if the mass of the objects increases?

The force increases because there is a direct relationship between mass and force.

The force increases because there is an inverse relationship between mass and force.

The force decreases because there is an inverse relationship between mass and force.

The force decreases because there is a direct relationship between mass and force.

What happens to the gravitational force as the distance between objects (in space) increases?

The force decreases because there is an inverse relationship between $$F_g$$ and distance.

The force increases because there is a direct relationship between $$F_g$$ and distance.

The force increases because there is an inverse relationship between $$F_g$$ and distance.

The force decreases because there is a direct relationship between $$F_g$$ and distance.
