### Electrical resistance and Ohm’s law

Electrical resistance and Ohm’s law In my last post, I wrote about a fairly extensive piece on charge, current, and voltage in electricity. I said some things have something called charge and some things do not. Like charges repel, opposite charges attract. Electrons all

### Physics Practice Questions – Why Are They So Essential?

Physics Practice Questions. Think of all the homework and class assignments you have been set. How many of them involve working through exam questions? Some? Most? All?   Chances are, if you’re studying Physics A-level or GCSE you’ve been set work that includes previous

### What is Electricity?

What is Electricity? A lot of students struggle with this topic and just like with many topics, the problem lies within the foundational understanding. A student may be struggling with how voltage and current behave in series and parallel circuits but has not noticed that

### You will be a different person after reading this post

### Implicit differentiation and its use in derivatives

Implicit differentiation is one of the types of derivatives used widely in differentiation calculus is a sort of derivative in which the derivative of the equation must be determined. Differentiation calculus is a type of calculus that is mainly used to find the rate

### How to Write Good Physics Coursework – A Teacher’s Guide

Physics Coursework   What have Special Relativity, Newton’s laws and electromagnetic induction got in common? They would have all scored poorly if they were entered as physics coursework at sixth-form. It matters not a bit that they were pioneering, ground-breaking physics; in the context

### Performing a Titration Calculation (part 3 of 3)

Completing a titration calculation This is the third post in my series on moles. This one covers performing a titration calculation. You can click here to see part one and part two. In this post, we look at how to use a titration result

### More on Moles (part 2 of 3)

Part 2 of 3 on moles Today’s blog post will be the second part of a three-part series on a Chemistry topic called moles. I wrote the first part called ‘What is a Mole?’ recently and I would suggest reading that first, but essentially

### What is a mole?

No, not that type of mole!   This post is most suited to those of you studying GCSE Chemistry and confused about the topic of moles, which is within the area of Chemistry known as quantitative chemistry. As a private tutor, I have become
