Homework :

Torque Ex 4G, p. 125-129

Torque

Also called:

• Rotational Force
• Moments about a point
• Units are Newton meters (Nm)

 

𝝉 = F L⦜

• 𝝉 - Torque (Rotational Force). Product of Force (F) times leaver length (L) at right angles (⦜) to the force.
• Do not confuse Torque with Work! With Work the Force and distance are parallel, (W = F d∥). Torque Nm are not Joules!

In Level 2 Physics, you will be dealing with static systems that are in equilibrium. They are balanced so the net torque is always zero (Newton's First Law).
