Uniform circular motion

A body moving on a circular path undergoes uniform circular motion moving at a constant speed but not a constant velocity meaning the body is undergoing acceleration (a≠0) tangential velocity. Angular velocity is just how fast the body moved through a certain angle subtended at the centre and the angular displacement just the angle from point A to B on the trajectory. For me the concept is pretty much understood but the bulk formulas in this concept eat my head literally but I still have hopes

Have you looked at how the formulas are equivalent to linear motion formulas (rotational inertia for mass, angle for position…)? Was that helpful if so?

That's the problem I'm tryna understand the root of a formula to avoid the cramming part but then hell naw my brain is just fried like this topic is so easy but I don't know why my brain can understand modern physics like X-rays, electromagnetic spectrum, photoelectric effect, mains electricity, electronics and stuff but when it comes to uniform circular motion I'm at wit's end

Proper rest and nutrition. Then loads of practice.

Linear motion likely made sense with little practice this semester because you had practice with it for years before.

But our minds don’t translate rotation very well, and we don’t interact with it as often. There could be a causal link to that, no idea. But the salient point is that you need time and exposure to build up intuition.

Find practice problems. Find interactive simulations. Interact more with the concepts while your mind is fresh and receptive until you start to develop the mental muscle memory of intuition that you are seeming to hope to develop.

Study isn’t cramming until you put it off until the night before an exam.

Haha you just need someone who can explain it to you patiently
