This downhill acceleration has a vertical component. Along the x-axis is uniform velocity, which is responsible for the horizontal particle, also known as the forward motion.ДЄlong the y-axis: uniform acceleration, which is responsible for the particle's vertical (downwards) motion. In a projectile motion, two separate rectilinear motions occur at the same time:ДЄ particle's horizontal and vertical projectile motions are accelerated in the following ways: When a particle is sent into the air at a certain speed, gravity's acceleration is the only force acting on it during that period (g). In such a situation, the particle's path is known as a projectile, and its motion is known as the projectile motion. When you throw a particle in an oblique path near the surface of the earth, it follows a curved route with constant acceleration. 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 objectвЂ™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 EarthвЂ™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:ДЄ projectile which is left to free fall from a considerable heightДЄ projectile which is launched directly upwardsДЄ 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. The angle of the trajectory in a given point is the same as the angle that the velocity vector form with the horizontal at that point.We all know from NewtonвЂ™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.

Once the strong> flight time is obtained, simply substitute in the equation of position of the horizontal component. It is the maximum horizontal distance, from the starting point of the motion to the point in which the body hits the ground. That is, the flight time is the time required for the height to become 0 (the projectile reaches the ground). It is calculated for y = 0, the vertical component of the position. From that time, and from the equations of position, we can calculate the distance to the origin in the both axes, the x-axis and y-axis. Starting from the equation of velocity in the y-axis, and making v y = 0, we get the time t that it takes the body in get to this height. This value is reached when the velocity in the y-axis, v yВ , is 0. On the other hand, frequently in exercises, you would be asked for some of the following values. On the other hand, to know which trajectory the body follows, that is, its equation of trajectory, we can combine the above equations to eliminate t, getting:ДЄs expected, this is the equation of a parabola. The equation of position of the projectile motion is given by:
