Screw theory

Okay, imagine you have different toys to play with like Lego blocks, dolls, balls, and cars. Each toy has a different way to move or work.

Now, let's focus on the cars. You can make them move forward, backward, turn left or right, and even open the doors. But, have you ever seen how the wheels or the doors of a car move when you do these things?

That's where screw theory comes in. It's a way of explaining how different things move or work when they turn, slide, or rotate. It looks at the relationships between all the parts and the forces that make them move.

So, if we look at the wheel of a car, it rotates on an axis or a point. Screw theory helps us understand how the force of the engine makes the wheel turn and how the shape of the wheel affects the car's movement. We can even use screw theory to explain other things like how the door of the car opens and closes, and how it relates to the other parts of the car.

Overall, screw theory helps us understand how different things move and work together in a very precise and mathematical way.
