What is projectile motion?

Projectile motion is the motion of an object that is thrown or projected into the air and is subject only to the force of gravity and air resistance. The object follows a curved path known as a trajectory, which is determined by its initial velocity and angle of projection. The motion can be broken down into horizontal and vertical components, with the horizontal component remaining constant and the vertical component being affected by gravity. Examples of projectile motion include throwing a ball, shooting a cannonball, or launching a rocket.

Projectile motion is the motion of an object that is thrown or launched into the air, subject to only the force of gravity. The object is called a projectile, and its path is called its trajectory. The trajectory is a parabola, and the object's velocity is always tangent to the trajectory.

The range of a projectile is the horizontal distance it travels before it hits the ground. The height of a projectile is the vertical distance it travels before it reaches its maximum height. The time of flight of a projectile is the total time it takes to travel from its launch point to the ground.

The equations of motion for a projectile are:

- x = v0t
- y = v0t - 1/2gt^2
- v = v0 - gt
- a = -g

where:

- x is the horizontal distance traveled
- y is the vertical distance traveled
- v0 is the initial velocity
- t is the time
- g is the acceleration due to gravity
