Gravity attracts masses towards one another. Near Earth's surface, freely falling objects accelerate at about 9.8 m/s² when…
An electric field surrounds a charge and exerts forces on other charges. Field lines point from positive to…
A magnetic field surrounds a magnet or current-carrying conductor. Field lines run from north to south outside a…
Moving electric charges create magnetic fields, while changing magnetic fields can induce voltage. These effects underpin motors and…
Measurements contain uncertainty from instruments and observation. Repeated readings, calibration and correct units help identify and reduce errors.
A simple measuring instrument needs a reference scale and calibration. Comparing readings with a known standard reveals zero…
Photovoltaic cells convert sunlight directly into electricity, whereas solar thermal collectors capture sunlight as heat for water or…
Solar panels generate electricity from light; solar collectors absorb heat. Orientation, shading and maintenance affect how effectively each…
Sensors detect changes in light, temperature, movement or pressure and turn them into usable signals for monitoring, alarms…
Spreadsheets organise experimental readings and calculate averages, graphs and trends. Reliable analysis begins with accurate data and clear…
Machine learning can recognise patterns in large physics datasets, but its results depend on the quality of training…
