Short explanation

Within Nuclear fusion (physics only), this learning objective asks you to (physics only) explain that high temperature is needed to overcome electrostatic repulsion between nuclei. Focus on the approved ideas physics only, high temperature and connect them clearly to Nuclear fission and fusion. A strong response should state the relevant particle, radiation, isotope, decay, half-life or nuclear-equation idea, then explain how it answers the exact command word. Avoid swapping nearby concepts such as atomic number and mass number, isotope and ion, alpha, beta and gamma radiation, or contamination and irradiation. This is a Physics-only point, so keep the answer tied to the AQA Physics specification.

Why it matters

This objective helps connect Nuclear fusion (physics only) to exam-style questions, flashcards, and revision notes for Nuclear fission and fusion.

Common mistakes

Misunderstanding Electrostatic Repulsion: Emphasize that high temperature provides the kinetic energy necessary for nuclei to collide with enough force to overcome their repulsive forces, enabling fusion.
