What is an Angle-Launched Projectile? Angle-launched projectiles are objects projected at an angle to the horizontal. Their motion begins with both an x- and y-velocity component. Projectiles have no horizontal acceleration and a vertical acceleration of 9.8 m/s/s, ↓.

Projectile is a body thrown with an initial velocity in the vertical plane and then it moves in two dimensions under the action of gravity alone without being propelled by any engine or fuel. Its motion is called projectile motion. The path of a projectile is called its trajectory.

Types of Projectile Motion. There are different types of projectile motion based on the direction of the initial velocity of the projectile. The three main types are vertical projectile motion, horizontal projectile motion and oblique projectile. Let us learn them in detail.

Projectile motion is a special case of two-dimensional motion. A particle moving in a vertical plane with an initial velocity and experiencing a free-fall (downward) acceleration, displays projectile motion.

Projectile motion is the motion of an object thrown (projected) into the air when, after the initial force that launches the object, air resistance is negligible and the only other force that object experiences is the force of gravity. The object is called a projectile, and its path is called its trajectory.

So our equation for the launch angle of the projectile is 𝜃 equals the inverse sin of the square root of two 𝑔ℎ divided by 𝑉. All that's left to do is to substitute our known values of 𝑉, 𝑔, and ℎ into this equation to calculate 𝜃.
