We may not know it, but averages affect our lives every day. Designers and manufacturers use averages to make our houses, cars, shoes and airline seats safer and more comfortable(ish). But calculating averages is way more complicated...

Will this be the last video I make about SI units? Quite possibly. There's something about being so precise and defining the systems within which science works. When we can more accurately and routinely measure a kilogram, a mole, a...

The rate of doing work, or of converting energy.

Circular Motion Example 1

Mathcad is a tool to arrange, calculate, and visualize engineering calculations. A Mathcad sheet has values, equations, plots, and functions that are written and displayed in a manner that is similar to how they are written in a textbook...

I sit down with Zach Weinersmith from SMBC comics to ask him some physics trivia and logic riddles!

Mark Brent’s coffee run takes a turn for the worse when he has a nasty encounter with Negative Nancy! This lesson will discover the importance of distance-time graphs and displacement-time graphs for representing motion.

Deep underground, Carmen and Alexandra ‘Lexi’ Luthor perform a top-secret science experiment. Will they unlock the power to rival Vector Man? This lesson will perform calculations using the equations of motion for uniform acceleration....

This nugget explains about the acceleration,average acceleration and its SI units, veloocty-time graph and time-velocity graph.

With Pilot Mitchell’s help, Lotus Lang continues hunting for clues. Will she strike gold and pick up the lost trail? This lesson will lay the foundations for understanding acceleration and its close relationship with...

Field lines, potentials, equipotential lines and potential gradients – they sound similar but mean different things! With all these confusing terms, it would be much easier to kick back and watch some soccer (football). In fact, why...

We’ve all heard the saying, “what goes up must come back down.” But when we launch rockets and satellites into space, they (usually) don’t come back! Let’s prove this saying wrong, using Physics! This lesson will introduce and derive...

Mark Brent and Lotus Lang are Hopeless Ramentics – or so it seems. Things are about to explode! This lesson will discuss the differences between distance and displacement. Definitions included: distance, displacement, delta notation

Exam tip: one mark in the HSC Physics exam may come from using the correct units. So, if you write and use SI units in all calculations (a pretty simple task), you’ll get a free mark! If only the rest of the exam was that easy! This...

Exam tip: always show units when performing calculations, because missing units might be penalized by the markscheme! This lesson will continue our crash course on units, focusing on SI prefixes and simple unit...

Mark Brent and Lotus Lang are Hopeless Ramentics – or so it seems. Things are about to explode! This lesson will discuss the differences between distance and displacement. Definitions included: distance, displacement, delta notation

Learn about international system (SI) units.

Overview of units derived from the seven basic units of the International System of Units.

Mark Brent’s coffee run takes a turn for the worse when he has a nasty encounter with Negative Nancy! This lesson will discover the importance of distance-time graphs and displacement-time graphs for representing motion.

We all know that engineers need mathematics but we often don't talk about this in reverse. In this video I go over how engineering can come into play within problems that seem to be related to just math. <br/>

One of the best things about Newton was the way that he showed how natural phenomena abide by rigid mathematical principles. So much so that we can use mathematical equations to calculate how objects will actually behave. This equation,...
