1. Rotational motion, Newton's law

2. - The tendency of a force to rotate an object about an
axis, fulcrum, or pivot.
- A torque can be thought of as a twist to an object.
- Mathematically, torque is defined as the cross product of the lever-
arm distance and force, which tends to produce rotation.

Acceleration
α= dω / dt

5. Newton’s law for objects moving along a straight line describes the
relationship between the force applied to an object and its resulting
acceleration
Work: Wlm = ʃ F dx
= Fx
Wrot = ʃ τ d𝞱
= τ𝞱
Power: Plm = dW/dt
= F (dx/dt)
= Fv
Prot = dW/dt
= τ (d𝞱/dt)
= τω

In Watt's judgement, one horse can
do 33,000 foot-pounds of work every
minute.
