Conservation of energy (AQA A-Level Physics): Flashcards

Energy cannot be created or destroyed, only transferred

Remains constant (no energy enters or leaves)

$\Delta E_p = m \times g \times \Delta h$

$E_k = \frac{1}{2} m v^2$

$9.81$ m/s²

Kinetic energy transfers to gravitational potential energy

Zero (all KE converted to PE)

Energy transfers to surroundings as heat

Gravitational potential energy converts to kinetic energy

GPE at top equals KE at bottom
