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...

Video on Newton’s second law of motion
Hi and welcome to my video on Newton’s second law of motion. The second law is one of three laws published by Sir Isaac Newton in 1687. I start the video by...
Tutorial on Newton’s second law of motion
Hi and welcome to my tutorial on Newton’s second law of motion. My video on Newton’s second law explains how we can use the law to predict the forces required to control...
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
Newton’s first law of motion
Hi and welcome to my tutorial on Newton’s first law of motion. My video on Newton’s first law of motion explains how we may use the law to better understand the forces acting...
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...
Playing with equations
Here you can see me using a new tablet to explain how to use Newton’s second law to predict forces and accelerations. You will be able to see me using this in...
A Newton spring balance
Professor Mac is using a Newton spring balance in his experiments to illustrate Newton’s second law of motion. Do you know what it is? Well it is shown below. The balance contains...
