ROTATIONAL MOTION

What symbol is used to denote angular velocity?

• θ
• α
• v
• ω

What does the instantaneous angular velocity represent?

• Total angle rotated
• Time for one revolution
• Rate of change of angular position at an instant
• Number of revolutions per second

How is average angular velocity calculated over a time interval ∆t?

• ∆t/∆θ
• ∆θ × ∆t
• d²θ/dt²
• ∆θ/∆t

For a rigid body rotating about a fixed axis, what is true about the angular displacement of all particles in a given time interval?

• Displacement increases with radius
• Displacement decreases with radius
• All particles have the same angular displacement
• Displacement depends on mass

What is the direction of the linear velocity vector in rotational motion?

• Radially inward
• Radially outward
• Along the axis
• Tangential to the circular path
