Collisions in Two Dimensions (Leaving Cert Physics): Quizzes

Motion occurs in perpendicular axes

Separately to x and y directions

$v_x = v \cos θ$

$v_y = v \sin θ$

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

$\tan θ = \frac{v_y}{v_x}$

By ejecting mass in one direction

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

Only momentum

Both momentum and kinetic energy

Momentum is a vector quantity

Set up coordinate system
