Thermodynamics and engines (AQA A-Level Physics): Flashcards

Positively charged electrode

Negatively charged electrode

$L = L_0 \sqrt{1 - \frac{v^2}{c^2}}$

Packet of light energy

Minimum energy to eject electron from metal surface

Release of electrons from heated metal surface

Particles pass through energy barriers even without sufficient energy to overcome them

$\frac{\text{charge}}{\text{mass}}$

$F = 6 \pi \eta r v$

Time appears to pass slower for objects moving near speed of light
