• Ex 4C, p.105-107, Impulse ΔP = FΔt (earlier week)
• Ex 4G, p.125-130, Torque - Static Moments (this week)
Torque

𝝉 = F L⦜
𝝉: Torque (Nm)
F: applied Force (N)
L⦜: Length of lever at right angles to the applied force (m)


• Torque (Moments) in Level 2 Physics will involve Static Systems
• Therefore the Torques are balanced and the Forces are balanced - Newton's Laws of Motion apply to turning forces as well as linear forces
• PhET - Torque Balancing Act simulation
Bridge support forces moments


Torque (Moments anout a point)
Static (unmoving) systems will be used for this section. Therefore all forces, linear and turning, are balanced
