The equation for electrical energy is tricky because it contains four components whereas many of the common GCSE equations contain only three components - or can easily be reduced to three because one of the components can be treated as a constant. The best way to handle a four-component equation is to fill-in the values … Continue reading Electrical Energy Calculations
Experimental data
One of the most important skills that is required for success in physics is the ability to handle experimental data in an appropriate way. This includes everything from correct use of units and equations to identifying anomalies, finding averages and recording calculations with the proper number of significant figures. All of these skills are tested … Continue reading Experimental data
