Collisions in Two Dimensions (Leaving Cert Physics): Flashcards

Collisions at angles, not head-on

Momentum is conserved

Applied separately to x and y directions

$v_x = v \cos θ$

$v_y = v \sin θ$

$v = \sqrt{v_x^2 + v_y^2}$

$\tan θ = \frac{v_y}{v_x}$

Eject mass, gain momentum in opposite direction

$F = \frac{dp}{dt}$

Both momentum and kinetic energy

Only momentum, not kinetic energy

Momentum is a vector quantity
