ROTATIONAL MOTION

What is the primary factor that distinguishes rotational motion from translational motion?

• Speed of motion
• Mass distribution
• Presence of a fixed axis or point
• Applied force

Which law is analogous to F = ma in rotational motion?

• F = mv
• L = Iω
• τ = Iα
• v = ωr

What is the effect of applying a force along the line of the axis of rotation?

• Maximum rotation
• Slows down rotation
• No rotational effect
• Reverses rotation

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

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

What determines the magnitude of linear velocity in rotational motion?

• Only angular velocity
• Only radius
• Angular velocity and perpendicular distance
• Mass of the particle
