How Solar Panels generate electricity (in brief):

1. Let’s delve into a section of the solar panel. This section is called a solar cell.

2. The solar cells are made mainly with silicon, an element. Silicon as an element is made up of silicon molecules that have shared electrons. But when PHOSPHURUS atoms are added to the silicon structure, the there is one free phosphorous electron that is free to move around. Boron can also be added to silicon structure. The only difference is that there is a lack of one electron for very boron.

Circular motion:

A simple but fascinating subject. The basics:

• Increase in speed (around a circular trajectory i.e. a circular path/loci) results in the increase of deflection (at what direction is the resultant/net force of weight and string tension). 
• If the radius (the distance between the centre of the circular path e.g. roundabout, and the object in motion) is increase, the deflection will increase automatically.
