Why can displacement be negative but distance cannot?
A
a=−g=−9.8 m s−2a=-g=-9.8\text{ m s}^{-2}a=−g=−9.8 m s−2.
B
Displacement includes direction; distance is non-negative total length.
C
y=xtanθ−gx22u2cos2θy=x\tan\theta-\dfrac{gx^2}{2u^2\cos^2\theta}y=xtanθ−2u2cos2θgx2.
D
They occur over the same time interval.
