ROTATIONAL MOTION

In which direction is the angular velocity vector for counterclockwise rotation when viewed from above?

• Downward
• Horizontal
• Tangential
• Upward

In which direction is the angular velocity vector for clockwise rotation when viewed from above?

• Upward
• Horizontal
• Radially outward
• Downward

What is the significance of using r⊥ instead of r in rotational formulas?

• It simplifies notation
• It accounts for the effective radius in rotation
• It reduces computational error
• It is a standard convention

How does the magnitude of ω × CP depend on the vectors involved?

• ω + CP
• ω minus CP
• ω times CP since they are perpendicular
• ω divided by CP

What is the purpose of defining angular displacement?

• To measure linear distance
• To calculate force
• To determine mass
• To measure the extent of rotation
