It also requires considering other external forces like friction from aerodynamic drag or internal propulsion when the projectile motion is at a larger scale. Because of the object’s initial inertia, an external force is unnecessary to maintain the horizontal velocity of the object. The only force acting upon a projectile is gravity, which imparts a downward acceleration to the projectile. Study of such motion is called ballistics. A projectile, that is launched into the air near the surface of the Earth’s and moves along a curved path, or in other words a parabolic path, under the action of gravity, assuming the air resistance is negligible.
Projectile motion is the motion experienced by an object in the air only under the influence of gravity.

Projectiles can roughly be classified into three kinds:Ī projectile which is left to free fall from a considerable heightĪ projectile which is launched directly upwardsĪ projectile upwards at an angle towards the horizontal We can define a projectile as an object which is projected into the air with only downward gravitational force influencing it and continues its motion by the virtue of its own inertia. An object which is in motion in the air with no other force but gravity influencing it is a projectile. When we throw an object up, due to the force of gravity it eventually comes down. The object which is launched into the air is called projectile, and this kind of motion is called projectile motion. Due to the influence of gravity, that object takes a curve path forward towards the ground before it eventually stops after touching the ground. But since the object is also under the influence of gravity, it also dips down in the ground. Also, if you launch an object up into the air, it travels into the air due to its inertia of motion. Gravity influences any object suspended in the air to fall downwards, as in the case of fruits from trees. We all know from Newton’s Universal Laws of Gravity that any object on Earth is constantly influenced by gravity and pulled towards the center of the gravitational field, that is the center of the Earth.
