In projectile motion, the object experiences a larger vertical acceleration due to the force of gravity acting solely in the downward direction at 9.8 m/s², while its horizontal motion remains unaffected.
In projectile motion, the motion of an object is divided into horizontal and vertical components, which are independent of each other. In the absence of any significant air resistance, the only force acting vertically on the projectile is gravity. The force of gravity causes the object to undergo vertical acceleration, and this acceleration is constant and directed downward at a rate of 9.8 m/s².
The horizontal motion, on the other hand, remains unaffected by the force of gravity, resulting in a constant horizontal velocity. Therefore, while the horizontal acceleration is zero, the vertical acceleration is solely determined by the force of gravity, leading to a larger vertical acceleration in projectile motion.
