Projectile motion is the motion of an object that is launched into the air and moves under the influence of gravity alone.
The main components of projectile motion are the initial velocity, angle of launch, and acceleration due to gravity.
The range of a projectile is maximized at a launch angle of 45 degrees. As the angle decreases or increases from 45 degrees, the range decreases.
The time of flight of a projectile is directly proportional to the initial velocity. This means that as the initial velocity increases, the time of flight also increases.
The mass of a projectile does not affect its trajectory, as long as the air resistance is negligible. This is because the acceleration due to gravity is the same for all objects, regardless of their mass.
