Projectile Motion

Projectile motion is a fundamental concept in physics that describes the motion of an object in the air, subject only to the acceleration due to gravity.
It is a parabolic motion in two dimensions.

Horizontal Velocity

Horizontal velocity is the velocity of a projectile in the horizontal direction.
Horizontal velocity is constant throughout the entire trajectory of a projectile.
Gravity only acts in the vertical direction, so there is no horizontal acceleration.
The horizontal speed of a projectile remains unchanged, regardless of the launch angle, initial speed, or any other factors.

Vertical Acceleration

Vertical acceleration is the acceleration of a projectile in the vertical direction.
Vertical acceleration is equal to the acceleration due to gravity, approximately 9.8 m/s² on Earth.
The vertical acceleration is constant and affects the vertical component of the projectile's velocity.
The vertical velocity of a projectile changes direction and magnitude during its trajectory.
Before the object reaches its maximum height, the vertical velocity decreases.
At the projectile's maximum height, the vertical velocity becomes zero.
After the maximum height, the vertical velocity increases.

Key Concepts

Horizontal velocity is constant throughout the trajectory of a projectile.
Vertical acceleration is constant and equal to the acceleration due to gravity.
There is no horizontal acceleration, as gravity only acts in the vertical direction.
