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

Mac applies an unbalanced horizontal piston force to the block 21

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...

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...

Mac is writing on a tablet and showing how to use F=ma 0

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...

The spring of the balance is extended and a force shown on the scale 57

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...
