Question
Can a body in translatory motion have angular momentum? Explain.
✓
Answer
Yes, a body in translatory motion shall have angular momentum unless the fixed point, about which angular momentum is taken, lies on the line of motion of the body. This follows from $|\text{L}|=\text{rp}\sin\phi.\text{L}=0,$ only when $\phi=0\text{ or }\phi=180^\circ$ when $\phi=0\text{ or }\phi=180^\circ.$
