KS3 - Calculating Weight

KS3 - Forces Bundle

This bundle is a complete topic pack containing all powerpoints, student worksheets, challenge tasks, plenary activities, and answer sheets for the KS3 Physics topic “Forces”. It also contains many specially selected student-led activities on the powerpoints (particularly designed to make teaching the concepts of forces, fields, resultant forces, and weight, easier, more fun and student-led). There are also self-completing slides where answers can be clicked and move into the correct place (great for distance learning students and cover lessons). ### This bundle contains the following lessons: 1. Forces 2. Drawing Force Diagrams 3. Hooke's Law 4. Drag and Friction 5. Fields 6. Calculating Weight 7. Balanced and Unbalanced Forces ## Lesson objectives/outcomes: ### Lesson 1 – Forces #### Students should be able to: • Explain what forces are • Compare different types of forces • Describe how to measure forces and give the unit of force ### Lesson 2 – Drawing Force Diagrams #### Students should be able to: • Describe how forces are represented • Identify the direction a force acts on an object • Draw and/or label force arrows on diagrams for simple example ### Lesson 3 – Hooke’s Law #### Students should be able to: • Describe how forces deform objects • Describe how solid surfaces provide a support force • Investigate and use Hooke’s Law • Take accurate measurements • Plot a graph • Draw a line of best fit on a graph ### Lesson 4 – Drag and Friction #### Students should be able to: • Describe the effect of drag forces and friction • Explain how drag forces and friction arise • Describe how drag forces and friction can be reduced • Measure force using a newton meter • Record data in an appropriate table • use my observations to make a conclusion ### Lesson 5 – Fields #### Students should be able to: • Describe what a “field” is • Describe the effects of fields ### Lesson 6 – Calculating Weight #### Students should be able to: • Describe the difference between weight and mass • Calculate the weight of an object • Explain why weight is different on different planets • Convert units • Calculate values using a calculator ### Lesson 7 – Balanced and Unbalanced Forces #### Students should be able to: • Describe the difference between balanced and unbalanced forces • Explain why objects are in equilibrium • Explain the changing motion of objects • Calculate resultant forces in one dimension
