In my physics guide, I break down the difference between tangential speed and angular speed.

In physics class, they throw you equations like this: v=rω where both v and ω represent speed but it’s done so poorly people don’t know what they’re calculating.

v (m/s) represents the linear or tangential speed of an object that’s moving along a circular path. There is a direction associated with this velocity—which is the direction that the object would move in if its motion wasn’t constrained to the circle. This is why releasing a piece of string that you’re hurling in a circle causes it to fly off in one direction.

ω (rad/s) represents the angular speed of an object that’s moving along that same circular path. ω represents how quickly the object’s angular position θ changes per second. ω can point either counter-clockwise or clockwise depending on the direction that the object rotates.

You can check out the full guide here which includes an entire section on rotational motion including centripetal acceleration.

I’ve also released a Bundle, priced at a 20% discount, which combines the Physics Guide and the ‘Algebra for STEM’ guide into ONE product by compressing all of the relevant algebra used in physics—ranging from prealgebra through precalculus—into one product with physics! Make sure to purchase the complete bundle to master the foundations of physics!

Down below, you can read about each product separately!

Buy it Now: Understand Physics as a Science!

The reason why you’re struggling in physics is because the laws—such as Newton’s second law and conservation of momentum—are introduced as equations to solve problems before being properly understood and read as statements about nature.

That’s why I’ve created a guide which focuses on teaching you physics intuitively as a science so that you can understand how to read equations as statements of nature so that you understand what to do when you run into a new practice problem.

Version 1 just dropped last week (April 8th) and covers dimensional analysis, linear motion, calculus, and rotational motion.

Finals is coming in a few weeks so you better buy it ASAP (link in bio)!

Version 1 is out now!

The hardest part about math isn’t the raw calculations: it’s understanding what the math means when rearranging and graphing functions. Most students aren’t trained to interpret the math from a qualitative perspective which is why many students who are ‘good at math’ struggle in introductory chemistry, physics, and engineering courses.

That’s why I’ve created the Ultimate Algebra Guide for Science & Engineering Majors which covers all of the relevant concepts from algebra, trigonometry, and precalculus courses that are applicable for science & engineering majors condensed into a 700+ page guide!
