ROTATIONAL MOTION Quiz

• The particle has no mass
• The velocity keeps increasing
• The perpendicular distance from the point to the line of motion remains constant
• The angle θ is always 90 degrees

• No, never
• Yes, if net torque is zero but net force is not
• Only in vacuum
• Only for point masses

• Only magnitude
• Its color
• Its material
• Its magnitude and direction

• They are same
• Mechanical includes uniform motion, static means at rest
• Static has more conditions
• Mechanical is only for liquids

• They complicate analysis
• They are only for 2D
• They allow decomposition into independent scalar conditions
• They replace scalar laws
