Study Notes
Static Equilibrium
- The equation $F = 0$ represents the net force acting on an object in static equilibrium, which is zero.
- The equation $M = I\alpha = 0$ represents the net torque acting on an object in static equilibrium, which is zero.
Rotational Motion
- If a system is in static equilibrium, $\alpha = 0$ means that the object is not rotating or rotating with a constant angular velocity.
Newton's Second Law
- The equation $F = m\textbf{a}$ represents the relationship between the net force acting on an object, its mass, and its acceleration.
- When $\textbf{a} = 0$ in the context of Newton's second law, it means that the object is not accelerating, or in other words, it is moving with a constant velocity.
