Step 1 of 3

Linear Momentum and Collisions Linear Momentum and Collisions ● Momentum is a vector; its direction is the same as the direction of the velocity ● Momentum describes the relationship between mass and velocity for an object ○ p=mv ○ [p]=[m][v] ○ [p]=kgm/s Change in Momentum Impulse ● Newton’s second law, as we wrote it before: ○ ΣF =ma ● is only valid...
