Quick questions on Rotational equilibrium and Newton's first law in rotational form - AP Physics 1 Unit 5
3short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is q1?Show answer
A N weight hangs m from a pivot. Calculate the torque it produces about the pivot. [2 points]
What is q2?Show answer
A rigid body has zero net force but a net torque of Nm. State whether it is in equilibrium and what it does. [1 point]
What is not exploiting a smart axis?Show answer
Choosing the axis through an unknown force removes its torque, simplifying the equations. Failing to do so leaves you with extra unknowns.
