Question

What is the acceleration for projectile motion?
a. g, downward
b. none of these
c. opposite to the force of gravity
d. G, downward

Answer 1

Answer ⇒ g, downward.

Explanation ⇒ In case of the Projectile motion, acceleration in vertical direction is always downwards, and is same as the acceleration due to the gravity because projectile motion only means that the motion is completely under the action of the gravity.

But in case of the Horizontal, acceleration is zero, because it is the vertical component which becomes zero since the sine of angle 90 is zero.  (Mathematically).

If you want to feel it then it is zero because there is no force acting in the motion along the horizontal part of the Projectile motion.

Hope it helps.
