Chapter 06 Momentum
... When objects collide that are not moving parallel to each other, vector analysis is used to find the resulting momentum. When two dimensional motion is calculated, the momentum along the x-axis must be conserved, and the momentum along the y-axis must be conserved. Momentum of a system in the absenc ...

Group problem1. Solution:
... situation 2, before the collision and just after the collision (just before the 2 cars start skidding). Before applying the conservation of momentum, we can calculate the velocity of the 2 cars just after collision, we call this velocity vi. We use the work-kinetic energy theorem from situation 2 to ...

PHYS 1443 – Section 501 Lecture #1
... Consider a system with two particles that does not have any external forces exerting on it. What is the impact of Newton’s 3rd Law? If particle#1 exerts force on particle #2, there must be another force that the particle #2 exerts on #1 as the reaction force. Both the forces are internal forces and ...
