Non-UCM

What is centripetal acceleration in non-uniform circular motion?

• Acceleration directed towards the center of the circle

• Acceleration directed upwards from the circle

• Acceleration directed away from the center of the circle

• Acceleration directed tangentially to the circle

Explain the concept of tangential acceleration in non-uniform circular motion.

• Acceleration in the opposite direction of the velocity

• Acceleration along the tangent to the circular path

• Acceleration perpendicular to the circular path

• Acceleration towards the center of the circle

Provide an example of tangential acceleration in non-uniform circular motion.

• A bicycle moving in a straight line

• A ball rolling down a hill

• A car accelerating around a curve on a road.

• A person walking in a circle

A bottle of soap water is grasped by the neck and swings briskly in a vertical circle. Near which portion of the bottle do the bubbles collect

• Near the bottom

• In the middle of the bottle

• Near the neck

• Uniformly distributed in the bottle

If the speed of an object in circular motion is doubled while the radius remains constant, how does the centripetal acceleration change?

• It remains the same

• It becomes four times greater

• It becomes twice as great

• It becomes half as great

The unit of centripetal acceleration in the International System of Units (SI) is:

• m/s

• m/s²

• rad/s²

• rad/s

Which of the following factors does NOT affect centripetal acceleration?

• Speed of the object in circular motion

• Radius of the circular path

• Mass of the object

• Direction of the velocity vector

What is centripetal acceleration?

• Acceleration in a straight line

• Acceleration due to gravity

• Acceleration directed towards the center of a circular path

• Acceleration caused by friction

If an object is rotating with a constant angular speed, what is its angular acceleration?

• Zero

• non-zero

• Cannot be determined

• infinity

The relationship between angular acceleration (�α), angular velocity (�ω), and time (�t) is given by the formula:
