Tips And Tricks on Center of Mass, Impulse and Momentum
Tip #1
Linear momentum is conserved whenever external force is zero or in a two body system net external force is zero.Tip #2
Elastic collision occurs only in atomic or subatomic particles. In real world, collision is inelastic .Only collision between two ping-pong balls may be considered elastic. During elastic collision kinetic energy and linear momentum are conserved.
