Скачать или смотреть Work Done & Elastic Potential Energy Explained | GCSE Physics (Springs & Stretching)

In this GCSE Physics lesson, we explain what work done means and how energy is transferred when a force causes movement in the direction of the force.

You’ll learn how stretching or compressing a spring stores energy as elastic potential energy (also known as elastic strain energy), and how this energy is stored in the bonds between particles.

We cover:
• What “work done” means in physics
• How energy is transferred by forces
• Stretching and compressing springs
• Elastic potential energy explained simply
• The elastic potential energy equation: E = ½ k e²
• What the spring constant means
• Correct units for GCSE exam questions
• Common exam tips and mistakes to avoid

This lesson is ideal for GCSE Physics students studying:
AQA | OCR | Combined Science | Triple Science

📌 Key equation to remember:
Elastic potential energy = ½ × spring constant × extension²

📌 Units:
Energy = joules (J)
Spring constant = newtons per metre (N/m)
Extension = metres (m)

Perfect for revision, homework help, or last-minute exam prep.
