Let's talk about what you'll need out of math - the language of physics. #math #physics #physicsexplained

This post is all about math, because in order to go beyond purely conceptual physics, you need to be comfortable with mathematics. It’s how physicists talk to each other; it’s the language of physics.

So, what math skills do you need to successfully follow this blog? Since I’m starting out with algebra-based mechanics, you definitely need to be comfortable with algebra. You also need to know…

New blog post: Let's derive the kinematics equations - WITHOUT calculus! #physicsexplained #kinematics

Alright. We’ve defined our main concepts (displacement, velocity, and acceleration) and we’ve reviewed our algebra skills. It’s time to tackle the kinematics equations. The whole point of the kinematics equations is that they mathematically describe motion. Note: they do not explain motion! We’ll worry about explaining motion later because explaining why things happen is always more difficult…

New post! How do you feel about physics? #physicsexplained #physics

And I do mean this in a very literal sense: what are the primary feelings that come to mind when you hear the word, “physics”?

I ask my students this question on the first day of class, using pictures of my dog, Cheyenne (who, by the way, will make frequent appearances on this blog):

Physics makes me feel like:

Which one represents you?

I would love it of course if everyone…
