However, as soon as the bullet leaves the gun, gravity begins to exert a greater force and begins guiding it toward earth whether it falls or not depends entirely on how much opposing force is met along its path. The force from the ignition of gunpowder and the force of gravity combine to influence how long and in what direction the bullet travels. When an object is propelled through the air, numerous forces are acting on it simultaneously. This business applies to any kind of force exerted on an object since all forces produce changes in motion or state of motion. In physics, particularly mechanics (the study of physical change), an object’s speed is calculated by dividing its distance from an observer by how much time has passed if an object covers 30 meters in two seconds, then it has been traveling at 15 meters per second (15 m/s). This happens because of projectile motion. So, when we throw a ball horizontally into the air, it does a loop that goes up and over as if going in a parabola-like pattern and then comes back down. This part of the path is neither linear nor circular it is called projectile motion, and the path followed by the ball or the object is called its trajectory.

This path followed by the object appears to be like a parabola or U-shaped curve. When a ball is thrown up into the air, we see that it travels for some distance and then falls. When the maximum range of the projectile is R, at that moment its maximum height will be R/4.

The maximum height occurs when the projectile covers a horizontal distance that is equal to half of the horizontal range, i.e., R/2.

The angle between velocity and acceleration varies from 0° < θ < 180°, in the case of angular projection.

Angular momentum of a projectile = m u cosθ h, where h is the height.

Acceleration of projectile acts vertically downwards being equal to g and is constant throughout the motion.

At the lowest point, Linear momentum= mu.

At the lowest point, Kinetic energy= 1 2 m u 2.

At the highest point, linear momentum is m(u cos θ) and the kinetic energy is 1 2 m (u cosθ) 2.

Important Points Related to Projectile Motion

Horizontal Range: The horizontal distance traveled by the body performing projectile motion is the range of the projectile.

Projectile Trajectory: The path taken by a projectile in the air is called a projectile trajectory.

Point of Projection: The point from which the body is projected in the air is called the point of projection.

The velocity of Projection : The velocity with which the body is thrown is called the velocity of projection.

The angle of Projection: The angle at which the body is projected concerning its horizontal position is called the angle of projection.

For example, you might think about a football or cricket ball being thrown up in the air, traveling along its curved path before landing back down on earth. The other part of the path, however, is vertical and constant – this part is due to gravity. One part of the path is horizontal, where there is no acceleration. The path of a projectile can be discussed in two ways. Therefore, equations of motion can be applied separately at the X-axis and Y-axis to find the unknown parameters. In a projectile motion, the only acceleration acting upon is the acceleration due to gravity.

The Projectile in physics refers to an object that is in flight after being thrown or projected. Galileo was one of the first people to have ever described projectile motion This article will go through a basic introduction of Projectile Motion, it’s important terms and definitions, projectile motion equations, applications, and formulas. The solution is not obvious and can be approached in various ways. Given the initial velocity and angle of projection, it is a problem that has been studied since ancient times. What is Projectile Motion? Well, it is the motion of a projectile, such as a thrown ball, an arrow, or a baseball, concerning the force of gravity and masses of the projectile and the earth.
