ROTATIONAL MOTION Quiz

• It decreases
• It remains constant
• Tangential velocity increases proportionally
• It becomes zero

• It is irrelevant
• It measures force
• O helps define the full position vector, but only the perpendicular component contributes to torque
• It defines angular speed

• It measures angular acceleration
• It defines radius
• It is the angle between the force and the tangential direction
• It gives mass

• Radial direction
• Tangential direction
• Along the z-axis
• Opposite to velocity

• v = ω/r
• v = r²ω
• v = dθ/dt
• v = rω
