A perfectly inelastic collision is demonstrated and analyzed.

This video explains catalysts, exploring the concept of activation energy and how catalysts can lower it to speed up reactions. The video covers the use of catalysts in industry and domestic applications, including the catalytic...

We learned about ideal gases and the ideal gas laws, and we briefly touched on kinetic molecular theory, which puts these laws in context. But let's now go through this theory more rigorously, analyzing each postulate one at a time.

This video lecture focuses on how the volume of a gas affects its pressure. It first explains how temperature affects pressure and then delves into the example of how a fixed mass and temperature of gas stored in a piston react to...

Learn the basics about Diffusion of gases. How are gases diffused? What methods are used to diffuse gases? Find out more in this video!

Learn the basics about rates of reaction. Chemical reactions can only happen if reactant particles collide with enough energy. How do you measure the rates of a reaction? Find out more in this video!

Learn the basics about what is the Brownian motion? what is it used for? Find out more in this video!

It's time to learn a little more about a chemical reaction. How do molecules have to be arranged and how much energy do they have to collide with? What's a catalyst? Lots of great tidbits in this one.

Calculus based review of conservation of momentum, the momentum version of Newton’s second law, the Impulse-Momentum Theorem, impulse approximation, impact force, elastic, inelastic and perfectly inelastic collisions, position, velocity...

Five motorcyclists have been killed on GTA roads in just the past week. Metro Morning guest host Molly Thomas spoke with Jessica Whittaker, founder of the Look Twice Save a Life campaign, about what needs to happen to make roads safer.

It's been a deadly week on the roads in the Greater Toronto Area for motorcyclists. Five riders have been killed in separate collisions just this week. CBC Toronto host Shannon Martin speaks with OPP Sgt. Nicola Morris for tips on how...

Flaco was an owl who captured the city’s hearts when he escaped from Central Park Zoo and flew free for a year in New York City before dying this past February. 

A new report is recommending changes to the Manitoba intersection where 17 people were killed in a collision between a semi and bus last June. The province says it will follow through on one of three options — a roundabout, a wider...
