Learning Objectives

1.7.1 Energy

Core	Supplement
$1 State that energy may be stored as kinetic, gravitational potential, chemical, elastic (strain), nuclear, electrostatic and internal (thermal) 2 Describe how energy is transferred between stores during events and processes, including examples of transfer by forces (mechanical work done), electrical currents (electrical work done), heating, and by electromagnetic, sound and other waves 3 Know the principle of the conservation of energy and apply this principle to simple examples including the interpretation of simple flow diagrams$	$E_{\mathrm{k}} = \frac{1}{2}mv^{2}$
