Circular Motion and Gravity

The magnitude of the centripetal force acting on an object traveling in a horizontal, circular path will increase if the

• radius of the path is increased

• mass of the object decreased

• direction of motion of the object is reversed

• speed of the object is increased

What is the centripetal force that causes a satellite to move in a circle.

• Friction

• Gravity

• Acceleration

• Magnetism

If you could turn off a centripetal force,

would cause the object to fly off in a straight line.

Any force that causes an object to move in a circle is called a(n)

• centripetal force

• gravitational force

• unbalanced force

• balanced force

If you could turn off a centripetal force, inertia would cause the object to

• fall to Earth

• fly off in a straight line

• stop moving

• continue on its circular path
