In rigid body mechanics, things can change from being still to moving in a few different ways. Let's break it down:
When Push Overcomes Friction: Imagine you have a heavy box. It won’t move when you push it until your push is strong enough to beat the grip of static friction.
Applying Force Away from the Center: If you push on one side of an object instead of the middle, it can start to spin. This is called torque.
Changing Support: If you take away support, like a table under a book, the book will start to fall or move.
By understanding these situations, you can see how different forces and twists work together to make things move when conditions change!
