• The angular speed is maximum along x

• One
• Two
• Three
• Four

• Energy conservation
• Linear momentum conservation
• Rotational kinematics
• Conservation of total angular momentum when τ_ext = 0

• Any origin gives same result
• Only inertial origins are valid
• Both must be calculated about the same point
• The origin must be at rest

• It increases gradually
• It oscillates in space
• It remains constant
