Why is the vertical motion in aprojectile non uniform?

constant acceleration due to gravity

since acceleration is nonzero, the velocity changes.

Did you know?

Did you know that the vertical motion in a projectile is non-uniform? In the world of physics, a projectile is an object that is launched into the air and moves along a curved path under the influence of gravity. While the horizontal motion of a projectile remains constant, its vertical motion is affected by gravity, resulting in a non-uniform trajectory. As the projectile ascends, its vertical velocity slows down due to gravity's pull, causing it to decelerate. Conversely, as the projectile descends, gravity accelerates its vertical velocity, leading to an overall non-uniform motion. Understanding this concept helps us analyze and predict the trajectory of projectiles, which is essential in various areas such as sports, engineering, and even space exploration.
