Energy in 1D and Successive Collisions (Edexcel A-Level Further Mathematics): Flashcards

$m_A u_A + m_B u_B = m_A v_A + m_B v_B$

$e = \frac{\text{speed of separation}}{\text{speed of approach}}$

$e = \frac{v_B - v_A}{u_A - u_B}$

$e = \frac{v_{\text{rebound}}}{v_{\text{impact}}}$

$v_B > v_A$

Spheres will not collide again

$v = \sqrt{2gh}$

$h = \frac{v^2}{2g}$

No, kinetic energy is not conserved

Final velocities of previous collision
