Energy and fields written questions
Solve H2 Physics work, energy and power problems, then use worked solutions to review the calculation and energy reasoning.
Learning goals
- Track energy stores and transfers, then apply conservation of energy.
- Define work and derive and apply the kinetic-energy relationship.
- Derive Eₖ = ½mv² from the definition of work done by a force and the uniformly accelerated motion equations.
- Represent fields and relate work done by a field to potential-energy change.
- Draw field-line representations of uniform and radial gravitational and electric fields.
- Use force–extension graphs to determine elastic potential energy.
- Apply power, mechanical power and efficiency relationships.
