We are doing a Kinematics topic in Physics 11.  The concept of time is absolutely essential for this topic if we want to measure speed and acceleration. But what is time? How is it measured?

Mr Galileo Galilei was the first to come up with the idea that a pendulum could be used to keep time.  Before this he used his pulse! But  I wonder how many students have ever seen a clock that uses a pendulum to keep time?

We are doing a lab to find a pendulum that has a period of 1 second. Hopefully they will also answer the questions:

Does the mass of the pendulum bob make a difference to the period of the swing?

Does the height from which you let it go make a difference?

Does the length of the pendulum make a difference?
