Day 7

Spaced Revision

Come back to Rotational Motion of a Rigid Body: Moment of Inertia after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Torque is the vector product of position vector and force.
  • τ = rF sinθ gives the magnitude of torque.
  • Torque is maximum when force is perpendicular to the position vector.
  • Angular momentum is the cross product of position vector and linear momentum.
  • L = rp sinθ gives its magnitude.
  • Only the transverse component of momentum contributes.
  • A rigid body does not allow relative displacement between its particles under external force.
  • In rotation about a fixed axis, each point moves in a circle.
  • s = rθ, v = rω, and a = rα.

Common Mistakes to Avoid

Any large force produces large torque.

The radial component of force also contributes to torque.

Angular momentum is just mass times velocity, like linear momentum.

Memory Tips

Torque as a turning effect and a vector quantity

Magnitude of torque

Only transverse force contributes to torque

Torque at the hinge line is zero
