⭐️ Check out our website ⭐️ *** WHAT'S COVERED *** 1. The two definitions of power in physics. * Power as the rate at which energy is transferred. * Power as the rate at which work is done. 2. The key difference between 'energy transferred' and 'work done'. * Illustrated with examples of charging a phone versus pushing a car. 3. The equations for calculating power. * P = E / t (Power = Energy transferred / Time). * P = W / t (Power = Work done / Time). 4. The standard units for power, energy, work, and time. * Power in Watts (W), Energy/Work in Joules (J), and Time in seconds (s). 5. Worked examples for calculating power. * Comparing the power of two different lamps. * Calculating the energy transferred by a microwave by rearranging the formula. * Calculating the power used to do work on an object. *** CHAPTERS *** 0:00 Introduction 0:22 Power, Energy & Time 0:36 Power, Work Done & Time 1:21 Units for Power, Energy & Time 1:35 Worked Example 1 - Comparing Lamps 2:29 Worked Example 2 - Rearranging the Equation 3:27 Worked Example 3 - Calculating Power *** PLAYLISTS *** #GCSE #Physics #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
