Conservation of Momentum

In physics and engineering we use a law called the conservation of momentum to predict the motion of objects which are in a collision. We can also use it to design rocket...

Energy and Work – an Overview

In physics and engineering we use knowledge of a quantity called energy to understand nature and to design efficient machines and improve chemical processes. There are many different forms of energy. Some...

Newton’s Law of Universal Gravitation

I have released my video explaining Newton’s Law of Universal Gravitation. Newton’s Law of Universal Gravitation explains that there is a gravitational force between all objects. This gravitational force is an attractive...

Professor Mac is standing in front of a broken wall lying on the ground with the words "Professor Mac Explains Force" in large yellow text in the background. 14

What is Force?

  My video explaining force is now available. In it I explain the concept of force and the effect forces have on objects through a series of high quality animated experiments. Force...

Professor Mac is standing in front of red letters which say "Newton's Third Law of Motion" 0

Newton’s Third Law of Motion

  Quickly learn Newton’s third law of motion…. Action and reaction forces. Simple to say but confusing to use. Which force is the action force? Which force is the reaction force? How can...
