If you want to describe the motion of a moving body, you have at hand three important physical quantities: speed, velocity and acceleration. How is each one of them defined? What's the difference between average and instantaneous velocity? The answers and more in this third episode.

This episode is also available at blip.tv and on my Youtube channel.

The topics covered in this second episode are: displacement, vector addition, vector subtraction, products of vectors, components of a vector.

I'm a teacher and this is my podcast about physics. I'm currently teaching physics in a school in Warsaw, Poland. IB Physics Help video podcast is designed to provide my students with an alternative revision resource. In our school we follow the IB curriculum. However, I hope that anyone studying physics in secondary school will find this podcast useful.
