Collisions
Definition
Two objects meet in opposite direction
Momentum is conserved
Elastic collision
Definition
Two objects collide and bounces back
m 1 u 1 + m 2 u 2 = m 1 v 1 + m 2 v 2
Kinetic energy is conserved
Inelastic collision
Definition
Two objects collide and stick together
m 1 u 1 + m 2 u 2 = v ( m 1 + m 2 )
Kinetic energy is not conserved
