Centripetal Force: The Force Keeping an Object on a Circular Path

The video tutorial explains the concept of centripetal force in circular motion. It describes how this force acts at a right angle to the direction of movement and is provided by a string in a curved path scenario. When the inward force is removed, the object stops moving in a circle and continues in a straight line.

What is the path of an object moving under the influence of centripetal force?

• Straight line

• Circular path

• Zigzag path

• Random path

How does centripetal force act in relation to the direction of movement?

• In the same direction

• Opposite to the direction

• Parallel to the direction

• At a right angle to the direction

Which of the following is NOT a characteristic of centripetal force?

• Acts in the same direction as movement

• Is necessary for circular motion

• Keeps an object moving in a circle

• Acts at a right angle to movement

What provides the centripetal force in the example discussed?

• Gravity

• Air resistance

• Friction

• The string

What happens to the hammer when the inward force is removed?

• It moves in a zigzag path

• It continues in a circular path

• It moves in a straight line

• It stops moving
