Projectile motion occurs when a force is applied at the beginning of the trajectory for the launch (after this the projectile is subject only to the gravity). The path followed by the object is called its trajectory. Projectile motion is a form of motion where an object moves in a parabolic path. The object is called a projectile, and its path is called its trajectory. In this atom we will discuss the basic equations that go along with them in the special case in which the projectile initial positions are null (i.e. 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. In a previous atom we discussed what the various components of an object in projectile motion are. 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. Projectile motion only occurs when there is one force applied at the beginning on the trajectory, after which the only interference is from gravity. An object which is in motion in the air with no other force but gravity influencing it is a projectile. The path that the object follows is called its trajectory. Projectile motion is a form of motion where an object moves in a bilaterally symmetrical, parabolic path.
symmetrical: Exhibiting symmetry having harmonious or proportionate arrangement of parts having corresponding parts or relations.trajectory: The path of a body as it travels through space.The horizontal displacement of the projectile is called the range of the projectile, and depends on the initial velocity of the object.When the projectile reaches a vertical velocity of zero, this is the maximum height of the projectile and then gravity will take over and accelerate the object downward.By studying projectile motion, students can develop their analytical and problem-solving skills and gain a deeper appreciation for the physical world around them. This depends on the initial velocity of the projectile and the angle of projection. Physics Education: Projectile motion is a fundamental concept in physics education, as it is used to introduce students to the laws of motion, kinematics, and gravity.
