Professor Mac stands beside a wall which has the words action and reaction sprayed on it 0

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 4

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...

Professor Mac is showing a spring balance supported vertically from a frame 0

Working on a spring balance

Hi.  I’m currently working on my next video which will explain how a spring balance measures force.  I will be discussing Hooke’s law as well as elasticity and demonstrate how to create...

Mac is looking at a large block sitting on the frictionless surface below a small block 3

What a big block!

I am using different sizes of block to show the relationship between force, mass and acceleration.  This is the latest screen shot from the video on Newton’s second law of motion. Mac

Coloured blocks are used to show the change in position of the wooden block 0

Pulling blocks is all in a day’s work

Here are some screen shots of me accelerating a block along a frictionless surface to demonstrate how forces accelerate objects.  The coloured blocks are snap-shots of the position of the wooden block at one second...
