## Work Done By Friction (Physics 1 Problem Solution)

Having a hard time calculating the work done by friction? Turns out all it takes is a few FBDs, a little trig, and understanding the work equation. In this post and video, we go through a solution to a work done by friction (and work done by gravity) physics problem involving a man, an incline Continue Reading

## How To Focus On Homework: 2 Steps To Getting It Done FAST

I think we can all safely agree: Homework can be a royal pain (I’m looking at YOU, ridiculously long WebAssign problem sets). It takes forever to finish, especially when you don’t really know how to focus. It leaves you feeling tired, frustrated, and wondering whether you’ve actually learned anything at all, despite all that time Continue Reading

## How To Conquer Finals Week: My Secret 4-Step Formula

We all know finals week (in all it’s stress inducing glory) is the most crucial time of year. But does it have to be so insane? I say no, and here’s why. Finals is the time of year that you need to focus the most. The large majority of your grade is about to be Continue Reading

## Gravitational Potential Energy Examples (Physics 1 Breakdown)

Does reading through gravitational potential energy examples in your textbook make your brain want to explode? In this video I break down a Physics 1 exam problem that covers gravitational potential energy, orbits, escape velocity, and all the relationships between them that you’ll need to know. Problem Statement A space station of mass 400,000 kg Continue Reading

## How To Focus On Studying: Boost Your Willpower (In 4 Steps)

All of us want to know how to focus on studying consistently, but often it’s almost impossible to do. Want to know how to do it, and why willpower is the key to staying focused while studying? We’ll cover that in this video. Tareen writes… If you’re like Tareen and you have trouble staying focused Continue Reading

## Good Places to Study (Does Your Environment Matter?)

What are some good places to study? Does study environment matter? The research is in, and what it says is quite interesting… So in today’s video I answer a question about whether there’s actually such a thing as a “best” study location, or whether you’re just as well off on the couch. Then, I’ll offer Continue Reading

## Change In Momentum Problems (Physics 1 Solution Breakdown)

Change in momentum problems usually involve figure skaters, bullets, and other ridiculous scenarios. But don’t be fooled by the flash and dance – there’s a method to the madness. And in this video I go through an example of a conceptual change in momentum problem from a Physics 1 exam, step-by-step. Change In Momentum Problem Continue Reading

## Physics 2: How To Decode Electricity And Magnetism

Physics 2 (electricity and magnetism) can be a cruel bitch of a course. If you’ve ever come across a circuit with a resistor, capacitor, and inductor in series with some sort of complex switching mechanism in between them, and then are asked to graph the voltage or current over time, then you’ll know what I’m Continue Reading

## How to Pay Attention in Class: 4 Tips for Boring Lecture

Most of us want figure out how to pay attention in class more often, but it’s tough, especially during that horrible, boring lecture you’ve got coming up next. So let me know if this sounds familiar… You’re sitting there, and the professor is scribbling non-stop on the board. Symbols, diagrams, equations; you really have no Continue Reading

## Molarity Problems (Chemistry 1 Exam Solution Breakdown)

In this video I go through how to break down molarity problems (pulled from an actual general chemistry 1 exam), and understand the relationship between molarity, moles and molecular mass. On the surface it seems like a very straightforward problem. There’s not a lot of work involved here. But if you’re not solid on it Continue Reading
