GENERAL KNOWLEDGE

Detailed explanation-1: -Projectile motion is the motion of an object thrown (projected) into the air when, after the initial force that launches the object, air resistance is negligible and the only other force that object experiences is the force of gravity. The object is called a projectile, and its path is called its trajectory.

Detailed explanation-2: -Projectile motion is motion under the influence of gravity. If we stand at the edge of the roof of the Science Building and throw a ball up at an angle, it moves up and then down vertically while it moves horizontally. This is projectile motion.

Detailed explanation-3: -As a projectile rises towards the peak of its trajectory, the vertical acceleration will decrease; as it falls from the peak of its trajectory, its vertical acceleration will decrease.

Detailed explanation-4: -An object that is thrown, kicked or otherwise launched through the air is called a projectile. The study of how projectiles move through the air is called projectile motion. When a projectile is launched, it has an initial velocity (its speed and direction of motion).

Detailed explanation-5: -While a projectile has no vertical velocity at its peak, there is still a force of gravity acting upon it. In fact, gravity is the only force acting on a projectile throughout its motion.
