This resource contains experiments in physics and how to calculate parameters, uncertainty and representing the data graphically. Here is an example: A student measures the potential difference across a battery as 12.4 V and states that his measurement has a percentage uncertainty of 2%. Calculate the absolute uncertainty in his measurement. Kind Regards ENTER - ONE

This resource contains information on how to process experimental data. Measurements, significant figures and graphically representing information. Its useful in that experiments need to be done accurately and with precision. Data collection is important as information needs to be collected in such a way that is representative of the experimental results. I hope you enjoy using this resource. Kind Regards ENTER - ONE

This resource contains the theory, examples and real life applications of Maxima & Minima problems. Global and local points are illustrated as well as how these critical points can be used to solve problems. Here is a typical example: A rectangular lot is bounded at the back by a river. No fence is need along the river, and there has to be a 24ft opening at the front. If the fence along the front costs $1.50 per foot, & along the sides $1.00 per foot, find the dimensions of the largest lot which can be fenced for $300. We hope you enjoy and have fun using this resource. Kind Regards ENTER - ONE

This resource contains the theory, examples, questions and answers regarding Newton’s Law of Cooling. You will find a fun and colourful slide show that illustrates this theorem, as well as some interesting examples that will allow students to think critically and arrive at solutions. Here is a typical example: At 06:00 am, a detective finds a murdered body. Temperature of the body is 30 degrees celsius. By 08:00am the temperature dropped to 25 degrees celsius. Surrounding air temperature is 20 degrees celsius. Using the fact that when alive, the human body is 37 degrees celsius…find out when the murder was committed. Students will become real life detectives here. Equipping them with out of the box knowledge. Have fun! Kind Regards ENTER - ONE
