This simulation helps GCSE Physics students understand the concept of a system — an object or group of objects chosen as the focus when studying energy transfers — and how the system boundary separates it from the surroundings. Five scenarios can be explored: In every scenario, the dashed green boundary marks the system, with surroundings […]

GCSE Physics Exam Preparation: Systems In GCSE Physics, a system is an object or a group of objects that we choose to study. Everything outside the system is known as the surroundings. In exam questions, clearly identifying the system is essential for accessing full marks. A system can be open or closed. In a closed

Simulation of thermal conductivity This simulation helps GCSE Physics students visualise thermal conduction — the transfer of energy through a material from a region of higher temperature to a region of lower temperature. Students select from four materials (Wood, Glass, Steel, and Copper) and observe in real time how heat spreads across the rod from

Simulation of Energy dissipation in system change using a ball Energy Dissipation Simulation – “Where Does the Useful Energy Go?” This interactive physics demonstration shows what really happens to energy in a real-world system — using the everyday example of a bouncing ball. A brightly colored ball is dropped from a significant height onto a

Simulation of Energy dissipation in system change This simulation helps GCSE Physics students understand the concept of energy dissipation — that in every system change, energy is always conserved but spread into less useful forms. Using four real-world examples (light bulb, car engine, phone charger, and speaker), students can see how input energy is split
