Unit 7 Part 1

Unit 7 so far has been about momentum and collisions. The variable "p" represents the value for momentum which has the unit of mass*velocity or kg m/s. The way that this relates to collisions is that momentum is conserved. When two objects collide, the amount of momentum at the beginning and end of the collision remains exactly the same. The way we tested this was using our air track to collect data of different scenarios of collisions and recorded the velocities, used that and the mass to find the momentum, and checked to see that the momentum was conserved supporting the "law of conservation of momentum."
