Question
Which components remains constant in the instantaneous velocity components $v_x, v_y$ and in acceleration components $a_x, a_y$ of a projectile?
✓

Answer

In a projectile motion, the horizontal component of velocity $v_x$ remains constant while the vertical component of velocity $v_y$ changes due to acceleration due to gravity.
$
v_x=u \cos \theta, a_x=0 \text { and } a_y=-g
$
$\therefore v_x, a_y, a_y$ will remain constant
