H1 Physics: Energy and Fields structured questions

Learning objectives

• 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.
