A technician is testing the properties of a polyurethane tension band used in a robotic sorting system.
Explain what is meant when the tension band is said to have undergone elastic deformation.
The tension band has a spring constant of 240 N/m240\text{ N/m}240 N/m. Calculate the energy stored in its elastic potential store when it is stretched by an extension of 35 cm35\text{ cm}35 cm.
44 exam-style questions on AQA GCSE Physics 1.1 Energy changes in a system, and the ways energy is stored before and after such changes, covering 1.1.1 Energy stores and systems, 1.1.2 Changes in energy, 1.1.3 Energy changes in systems, and 1.1.4 Power. Each one has a worked solution and a mark scheme showing where the marks go.
