6.5 Forces - acceleration

Unit Summary

Forces are fundamental to understanding how objects move and interact. From the motion of vehicles to the forces acting on falling objects, these principles underpin much of physics and engineering. This unit explores key topics such as force and acceleration, weight and terminal velocity, forces and braking, and momentum ensuring students develop a robust understanding of Newtonian mechanics.

Mapped against the AQA GCSE Science specification, this unit is structured to build on prior knowledge from earlier years, reinforcing key concepts while introducing new ideas in a progressive and structured way. While schools can sequence the unit flexibly, it is designed with the assumption that knowledge in any given year builds on previous learning. Students will revisit and deepen their understanding of foundational ideas, such as Newton’s laws of motion, and apply them to increasingly complex scenarios.

Both substantive knowledge (the core scientific content) and disciplinary knowledge (working scientifically) are embedded throughout, with a clear emphasis on applying theoretical principles to practical investigations. The F=ma required practical is a key component of this unit, allowing students to explore how force, mass, and acceleration are related through hands-on experimentation. Other hierarchical elements of working scientifically, such as data analysis, evaluating methods, and drawing conclusions, are developed progressively. Prior learning is reinforced through reminders, prompts, and scaffolds to support students as they consolidate their understanding.

At Developing Experts, we are committed to supporting schools in delivering the National Curriculum while also broadening students' aspirations. Our curriculum is designed to challenge students by connecting classroom learning to real-world applications. The study of forces is not just theoretical—it has practical implications in fields such as automotive engineering, aerodynamics, biomechanics, and safety engineering. By exploring these applications, students gain insight into how scientific principles shape modern technology and innovation.

To strengthen these industry connections, we have collaborated with Rolls Royce Submarines, whose experts contribute to this unit. Their work in naval engineering and submarine technology relies on precise calculations of forces, acceleration, and momentum to ensure the safety and efficiency of underwater vessels. By integrating expertise from RR Submarines, students can see first-hand how the principles they learn in the classroom are applied in cutting-edge engineering fields.

This unit equips students with both the knowledge and skills necessary to succeed in GCSE Science, while also inspiring them to consider careers in physics, engineering, and beyond. For those interested in future opportunities, our careers zone provides insights into real-world applications and job prospects in industries where expertise in forces and motion is essential.
