Understanding how objects interact through forces is a cornerstone of physics. This unit introduces students to the distinction between vectors and scalars, and how different types of forces—such as contact, frictional, and gravitational—act between objects. Students will learn to represent forces using free-body diagrams and calculate resultant forces to determine an object’s motion. For higher tier students, this includes the use of parallelograms and resolution of forces to analyse motion in two dimensions.
Mapped to the AQA GCSE Combined Science: Trilogy specification, this unit builds on prior learning of motion and interaction from Key Stage 3. Students will explore gravity in more depth, including the concept of weight and the optional study of centre of mass. Forces and elasticity are introduced as part of the spring–extension relationship, including the required practical investigating Hooke’s Law.
Both substantive knowledge (core scientific concepts) and disciplinary knowledge (working scientifically) are integrated throughout the unit. Practical investigations provide opportunities for students to apply theory to real-world contexts, analyse data, and evaluate experimental methods. Key skills such as resolving forces, calculating resultant force, and interpreting graphs are embedded to support progression.
At Developing Experts, we aim to deliver a curriculum that not only meets the National Curriculum and AQA exam board requirements, but also broadens students’ curiosity and aspirations. The study of forces is more than academic—it connects directly to real-world applications in fields like structural engineering, biomechanics, robotics, and aerospace. Through this unit, students gain insight into how fundamental physical principles underpin technology and innovation.
This unit prepares students with the knowledge and skills essential for success at GCSE level and beyond, while offering a glimpse into careers where an understanding of forces is key. Our Careers Zone complements learning with real-life applications and career insights, helping students make meaningful connections between classroom science and the wider world.
