In Physics there are a number of equations and formulas for students to grasp. In this short session we will look at the useful energy transfers in devices and how to use the equation for efficiency in calculations. Applications in exam questions will be highlighted. These 5 minute, short burst classes give students the chance to practise solving the equations and allows them to excel in their in future learning.
