**Important Equations:**

4. Torque = Force in Direction of Motion x Distance ; Torque = Distance x Force x Sinθ

6. During Translational Equilibrium the Sum of Forces = 0

7. During Rotational Equilibrium the Sum of Torques = 0

8. Force of Gravity = (Universal Constant of Gravitation x Both Masses) /Distance Between Masses

^{2}

*The Universal Constant of Gravitation (G) = 6.67x10-11N(m/kg)
