ROTATIONAL MOTION

How does symmetry influence the location of the CG?

• It has no influence
• It shifts the CG randomly
• It places the CG at the geometric centre for uniform objects
• It hides the CG

How is the CG related to the point of support in a balanced object?

• They are always different
• They are unrelated
• They must coincide for stable balance
• They repel each other

What is the direction of gravitational torque on a particle relative to the CG?

• Always upward
• Always downward
• It has no direction
• It depends on the particle's position relative to the pivot

Can the CG lie outside the physical material of the body?

• No, it must be inside
• No, it vanishes
• Yes, in objects with hollow or irregular shapes
• Yes, but only in liquids

Why is the CG important in engineering design?

• It reduces cost
• It increases speed
• It affects appearance
• It affects stability and balance of structures
