GCSE Physics - Density - Equation | How to Calculate Density Experimentally (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. The concept of density * Defining density as the mass per unit of volume. * The formula for calculating density: Density = Mass / Volume. 2. Units of density * Standard units (kilograms per metre cubed, kg/m³). * Common alternative units (grams per centimetre cubed, g/cm³). * How to convert between different units of density. 3. Calculating density, mass, and volume * A worked example showing how to rearrange the density equation to calculate volume. 4. Measuring the density of a solid experimentally * How to measure the mass of a solid using a balance. * How to find the volume of a regular solid by measuring its dimensions. * How to find the volume of an irregular solid using a eureka can and the displacement method. 5. Measuring the density of a liquid experimentally * A step-by-step method using a measuring cylinder and a balance. 6. How to improve the accuracy of density measurements * Using larger volumes to minimise the effects of uncertainty. * Taking multiple readings to calculate a mean and identify anomalies. *** CHAPTERS *** 0:00 What is Density? 0:29 The Density Equation 0:44 Units of Density 1:17 Converting Density Units 1:36 Density Calculation Example 2:14 Measuring the Density of a Solid 2:40 Measuring the Volume of a Regular Solid 3:09 Measuring the Volume of an Irregular Solid 3:58 Measuring the Density of a Liquid 4:29 Improving Experimental Accuracy *** PLAYLISTS *** https://youtube.com/playlist?list=PLidqqIGKox7VzYfPIVt8T09xOLNcolCe4&si=8JmDajxjtba6rdc3 https://youtube.com/playlist?list=PLidqqIGKox7UZ3mWhbHv2aA_1vnbsfRPq&si=q3hEKdA4v7kbfwMe https://www.youtube.com/playlist?list=PLidqqIGKox7UTimdJ3eFcnt6xL9GUt2a6 https://youtube.com/playlist?list=PLidqqIGKox7XPh1QacLRiKto_UlnRIEVh&si=orIUwL3o2jOoiYjT https://youtube.com/playlist?list=PLidqqIGKox7X5UFT-expKIuR-i-BN3Q1g&si=DcihOwUkd9oWbbdp https://youtube.com/playlist?list=PLidqqIGKox7WeOKVGHxcd69kKqtwrKl8W&si=Y8MsO-FK948jnxpS https://youtube.com/playlist?list=PLidqqIGKox7UVC-8WC9djoeBzwxPeXph7&si=-7i5Iq7yOeJrhtu6 https://youtube.com/playlist?list=PLidqqIGKox7VKJD2WxRhoKaI6JGLVean8&si=NH_Q1ujhVgACM2FU #GCSE #Physics #study #revision #school #exam #AQA #OCR #Edexcel
