ROTATIONAL MOTION

What is the direction of the linear velocity vector of a rotating particle?

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

How is angular velocity related to linear velocity in rotational motion?

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

What is the orientation of the plane of motion of a rotating particle with respect to the axis of rotation?

• Parallel
• At 45° angle
• Perpendicular
• Arbitrary

Where is the center of the circular path of a particle in rotation about a fixed axis?

• At the origin
• On the axis of rotation
• At infinity
• Outside the body

In rotational motion about a fixed axis, what is the path of each particle of a rigid body?

• Straight line
• Parabolic
• Circular
• Elliptical
