ROTATIONAL MOTION Quiz

• The z-axis plane
• The xy-plane only
• A plane perpendicular to the z-axis passing through the particle
• The plane of force

• It is the center of mass
• It moves with the particle
• It is the center of the circular path and lies on the axis of rotation
• It is arbitrary

• It halves
• It quadruples
• It doubles the angular momentum
• No effect

• W = FΔx
• Net work equals change in rotational kinetic energy
• W = τα
• W = Iα²

• When force is radial
• When force is at 45°
• When the force is tangential to the circular path
• When force is axial
