Mechanics & Materials (AQA A-Level Physics): Flashcards

$\rho = \frac{m}{V}$

$F = kx$

$p = mv$

$E = \frac{\sigma}{\epsilon}$ (stress/strain)

Total momentum constant in closed system w/o external forces

Equal opposite forces, parallel lines, creates rotation not translation

Max speed when resistive force equals driving force, zero accel

Total kinetic energy is conserved

$F = ma$

$F\Delta t = \Delta p$ (change in momentum)
