ROTATIONAL MOTION

What is the role of θ in torque calculation?

• It determines mass
• It determines r
• It determines the effective component of force
• It determines time

How is angular momentum affected if the particle is at the origin?

• It is maximum
• It depends on velocity
• It is zero
• It is infinite

Why is torque dimensionally similar to work?

• Both are vectors
• Both are scalars
• Both have dimensions M L² T⁻²
• Both cause motion

What is the effect of halving the force on angular momentum?

• Angular momentum doubles
• Angular momentum halves
• No direct effect
• Angular momentum becomes zero

What is the effect of doubling the position vector on torque, keeping F constant?

• Torque halves
• Torque doubles
• Torque unchanged
• Torque quadruples
