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
