1
New cards

momentum (p)

mv, units: kg . m/s

2
New cards

impulse

change in momentum, F by change in time, units: N.s

3
New cards

force relation to momentum and impulse

F = change in momentum over change in time

4
New cards

formula for all collisions

sum of initial momentum = sum of final momentum

5
New cards

formula of inelastic momentum

m1u1 + m2u2 = m2v2 + m1v1

6
New cards

completely inelastic collision formula

m1u1 + m2u2 = (m1 + m2)v

7
New cards

perfectly elastic collision formula (shortcut)

u1 + u2 = v1 + v2
