New GCSE AQA Physics lesson on ' Resolution of Forces' written in line with new AQA Physics specification. All questions provided with answers within power point.
The starter provides some simple combination of forces questions to review the subject of resultant forces - one question has two forces acting on different planes which pupils will be unfamiliar with and therefore how to solve - this prompts the lesson.
The intuitive resultant force and direction is highlighted but also how we need to calculate exactly what they are.
The parallelogram/geometric method is taught step by step with a worked example, this is done a second time with another example but with the class prompted to follow it and do the same on their own paper which also allows for discussion of difference in results.
A collection of questions allows pupils to practice use of this method.
This method is then used for inclined planes to explain frictional force acting to put object in equilibrium on inclined planes. Review questions again allow pupils to practice this.
Lesson Objectives:
- Review resolving simple combination of forces.
- Identify when forces are acting on different lines/planes.
- Calculate the resultant force on an object which has equal forces acting on different lines/planes.
- Calculate the resultant force on an object which has unequal forces acting on different lines/planes.
A worksheet is not provided as it is best for pupils to work on their own paper to define their own scales for this methodology.

Looks great. Looking forward to using in class.
A great help! Very concise yet detailed explanations. Thank you for sharing.
Brilliant . This helped me so much.
Good examples for students to practice each part of the lesson. A homework sheet to accompany the lesson would be great for the price. It is a very good ppt but a bit expensive without accompanying resources like a lesson plan or homework sheet.
