Why do Olympic bars spin?

There’s something truly mesmerizing about watching an Olympic bar spin. But why does it rotate in the first place?

The answer has to do with the physics of rotational motion. When you lift a weight, you create a torque or rotational force on the bar. This force is what makes the bar spin around its axis.

The faster you lift the weight, the faster the bar will spin. And if you let go of the weight suddenly, it will continue spinning for a while before coming to a stop.

So next time you’re at the gym, take some time to watch those Olympic bars turn and marvel at all that physics magic!
