What is Work?

I'm sure tons of things come to mind when you hear the word work. Most of them are probably things like a job, or homework, chores, or keeping your mouth shut when that one relative is rambling about some new conspiracy at the family Christmas get-together. When it comes to science, work has a very specific, very mathy, meaning.

Teaching as a Profession

American school districts have found themselves in a mad dash for solutions as the fallout from a long-predicted threat has breached their hallways, sending shockwaves through classrooms across the country. The national teacher shortage has arrived. Too many states, Minnesota included, the solution is simple: lower the strict licensing and professional requirements, thereby making it … Continue reading Teaching as a Profession

What is Air Resistance? + Terminal Velocity

No matter where you are on earth, gravity is basically exactly the same. So why then does a bowling ball hit the ground before a feather?

What is Newton’s Third Law?

Newton's Third Law of Motion is my personal favorite. Why? Because it serves a dual purpose as good life advice. It goes like this. When you apply a force, expect an equal amount of force to be applied back. It also just so happens that Newton's Third Law is also one of the most fun … Continue reading What is Newton’s Third Law?

What is Newton’s 2nd Law of Motion?

Newton’s 2nd Law of Motion is probably the most confusing of the three, at least in how it’s defined. Why? Because it is defined in a few different ways. No matter how you put it, the 2nd law describes the “how” of it all. How are force, mass, and acceleration related? To get a better … Continue reading What is Newton’s 2nd Law of Motion?

What is Gravity?

You attract the universe, and the universe attracts you. Everything you see, and everything you don't, as long as it has a mass, is affected by gravity. From the phone sitting next to me as I type this, to my cup of tea. From me to Jupiter, nearly 465 million miles away (driving 60 mph, it would take about 885 years to get there).

What is Friction?

Stuff keeps going until something stops it. That's the basic idea of Newton's First Law, right? A ball hitting a wall or something. Yet, we also know that if we push a skateboard down the sidewalk, it's gonna stop eventually even if it never hits anything. So, why? Friction. The sciencey explanation is that friction … Continue reading What is Friction?
