By the end you’ll be able to

Describe energy stores and the ways energy is transferred (mechanical work, electrical work, heating, radiation), and use energy-transfer diagrams
Calculate kinetic energy (Eₖ = ½mv²), gravitational potential energy (Eₚ = mgh) and elastic potential energy (Eₑ = ½ke²), rearranging where necessary
Use ΔE = mcΔθ, and required practical: determine the specific heat capacity of a material with a joulemeter or voltmeter, ammeter and timer
