To keep things steady and balanced with objects that don’t change shape (we call these rigid bodies), there are three important rules to remember:
Net Force = 0: First, all the forces acting on the object need to add up to zero. This is like saying if you push one way with a certain force, there must be an equal push or pull in the opposite direction.
Net Torque = 0: Next, we have something called torque. This is all about rotation. Just like with forces, the total torque on the object should also be zero. This means that nothing should make the object start to spin.
Rigid Body: Lastly, don’t forget that these rules are for rigid bodies. This means the object keeps its shape no matter what forces are acting on it.
By keeping these rules in mind, you’ll have a strong base for figuring out problems about statics – or how things stay still!
