Mac sits in a red kart waving at the camera as he prepares to demonstrate Newton's third law of motion 2

How do you like my kart?

Hi. I’m making good progress on my latest video on Newton’s third law of motion. Chapter 1 is complete and I am about to start animation of chapter 2. This kart is...

Professor Mac is standing on a concrete floor and a red and blue arrow shows the forces acting on him and the floor 4

Feeling the force on my feet

Hi, Here is an image from my video on Newton’s third law of motion. When you are standing can you feel the force from the floor on your feet? Newton’s third law...

Law on a wall

Hi. I’m continuing to make progress on the development of my video on Newton’s Third Law of Motion.  Below is an image taken from the beginning of the video.  The law introduces the...

The red and white rocket has just lifted off the launch pad with orange and white smoke coming from the engine 0

3..2..1…We have liftoff

I have just completed the animation of my rocket “mac 1” during liftoff.  You can see the rocket as it lifts off the launch pad in the image below. The animation uses the Blender smoke...

Professor Mac is standing next to a white and red model rocket 0

How do you like my rocket?

Hi I have been modelling the rocket to be used in my video on Newton’s third law of motion. Here it is being prepared for launch   and here is a close-up view....

Newton’s Third Law of Motion

Hi, I have now started developing the next video in the series of Professor Mac explains Newton’s Laws of Motion.  Many viewers of my videos on YouTube, and readers of this website,...

Mac adds masses to the spring balance and the increase in spring extension is measured with the scale 4

Playing with springs is all in a day’s work

Hi.  Here is an image from my new video, which I’m currently developing, which explains the use of a spring balance to measure force.  You can see from the image that the...
