Professor Mac is stepping on to grey scales with two close-up pictures shown to the left. One of the scales shows his weight in kilograms and one in Newtons. 2

What do scales measure?

What do scales measure? The obvious answer is kilograms (or grams). That is what the reading on the scale indicates. However this is not what the scale is measuring. It actually measures force,...

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...

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...

A Newton spring balance

Professor Mac is using this in his experiments to illustrate Newton’s second law of motion. Do you know what it is?  Well it is a Newton spring balance.  The calibrated spring provides a measure...
