A horse gallops around a circular arena. The centripetal force on the horse is ___.

• directed outward

• directed forward

• directed toward the center of the arena

• direction cannot be determined

Where direction is the centripetal force for the rollercoaster when the rollercoaster is at the top of the loop?

• Towards the sky

• Towards the Right

• Towards the left

• Towards the ground

The centripetal force of satellites is the gravitational force because it is the force pointing towards the center of the satellite's circular path.

• True

• False

The diagram shows a stone tied to the end of a length of string and is whirled round in a horizontal circle . What provides the centripetal force on the stone?

• The weight of the string.

• The friction in the string.

• The tension in the string.

• The air resistance from the surroundings.

The _______________________ supplies the centripetal force requirement for the car to move in a horizontal circle. Without it, the car would turn its wheels but would not move in a circle (as is the case on an icy surface).

• friction force

• centrifugal force

• normal force

• applied force

For the marble in the plate activity, what force was acting as the centripetal force?

• Normal Force

• Gravitational Force

• Friction Force

• Tension Force
