# AP Physics

Two particles, each of mass m and speed v, travel in opposite directions along parallel lines separated by a distance d.
A)Find an expression for the magnitude L of the angular momentum of the two-particle system around a point midway between the two lines. Use m for the mass, v for the speed and d for the distance of separation.
B)Does the expression change if we change the point about which L is calculated?
C)Now reverse the direction of travel for one of the particles and repeat (A)
D)Does the expression change if we change the point about which L is calculated?
