using Excel’s LINEST function⤴

from @ fizzics

The period (T) of a simple pendulum can be calculated using where l is the pendulum length and g is the gravitational field strength. Using a single value of length and period, we can determine the acceleration due to gravity.  However, it would be better experimental practise to vary the length of the pendulum and ... Read more

higher assignment⤴

from @ fizzics

Your assignment will be based on an optoelectronics topic.  You will get some ideas for practical work by downloading this booklet. I have attached a copy of the Scholar notes for unit 3 of the CfE Higher course.  You will find background physics with appropriate energy band explanations on pages 103-142. Don’t print this document, ... Read more

particle accelerators⤴

from @ fizzics

An electric field can be used to accelerate charged particles. Conservation of energy tells us that work done by the electric field = change in the particle’s kinetic energy The speed of the particle can be determined if its charge and the accelerating voltage (potential difference) are known.  The notes attached to the end of this post ...
