ROTATIONAL MOTION

How does the center of mass behave in the absence of external forces?

• It stops
• It accelerates
• It moves with constant velocity
• It moves in a circle

What is the center of mass of a uniform circular disc?

• At the edge
• At the top
• At its center
• At the bottom

Why is the center of mass important in mechanics?

• It is only for statics
• It simplifies motion analysis
• It measures weight
• It determines size

What method is used to find the center of mass of continuous bodies?

• Differentiation
• Algebra
• Integration
• Graphing

How does the center of mass concept apply to real-world objects?

• It has no real-world application
• It only applies to space objects
• It determines balance and stability
• It is only for theoretical use
