ROTATIONAL MOTION Quiz

• When r is parallel to ω
• When r is zero
• When ω is zero
• When r is perpendicular to ω

• Radius of curvature
• Distance from center of gravity
• Moment arm
• Position vector from origin to the particle

• It calculates mass distribution
• It measures angular displacement
• It balances forces
• It leads to the derivation of v = ω × r

• v = ω + r
• v = ω · r
• v = r / ω
• v = ω × r

• Angular acceleration
• Centripetal force
• Torque
• The linear velocity of a rotating particle
