ELASTIC COLLISION IN ONE DIMENSION - CH4

what is Newton’s law of restitution

speed of separation of particles / speed of approach of particles = e

what is e?

the coefficient of restitution, always between one and 0

what is the value of e in a perfectly elastic collision versus a totally inelastic collision

e=1

e=0

when particles are moving towards each other, speed of separation or approach is

the sum of the speeds

when particles are moving away from each other, the speed of separation or approach is

the difference between the speeds

how can you use e in conservation of momentum?

you can form simultaneous equations with v1 and v2 by doing both separate methods normally and then combining the equations formed from them

e for when a particle collides with a smooth plane

speed of rebound / speed of approach = e

succesive collisions

find the unknown value that’s needed for the second collisions by solving the first normally, then just substitute these values into the second, but a final velocity for collision 1 will be an initial velocity in collision 2
