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 **    • KS3 Biology      • KS3 Chemistry      • KS3 Physics      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Physics #study #revision #school #exam #AQA #OCR #Edexcel
