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
