Under what circumstances is momentum conserved?
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 for objects that have constant mass. Here is a more general form, also useful when the mass is changing: ○ Impulse Example ● A 0.144 kg baseball moves towards home plate with a speed of 43.0 m/s where it is bunted. The bat exerts a force of 6.50x103N on the ball for 1.30 ms. The average force is directed towards the pitcher. What is the fin
