# Investigating Projectiles

Background:

A projectile is an entity which only has the force of gravity acting upon it. A projectile can be cast, fired, flung, heaved, hurled, pitched, tossed and thrown. A projectile can be anything as long as it has initial horizontal velocity that is not equal to zero which has the acceleration due to gravity. Projectile motion happens when an object projected with a force stops putting influence on the object after its launched, hence the only force being gravity. The trajectory is the path of the projectile. There are three types of projectile motion as the following.

Projectiles 1: When an object is dropped from rest at an elevation or fired from elevation with an angle of zero.

Projectiles 2: When the object is thrown at an angle from no elevation with a parabolic trajectory.

Projectiles 3: When the object is thrown upwards at an angle from a higher elevation

Each projectile had its own separate calculations and equations. Projectiles are a 2 dimensional because the motion of the projectile is all one. When calculating projectiles you must consider the acceleration due to gravity because that’s the single force acting upon it and assume that there is no air resistance.

When analyzing Projectile you usually are trying to find the initial velocity, initial horizontal velocity, initial vertical velocity, range which is how far the projectile has travelled, the final vertical and horizontal velocity, time of flight, height of flight, time taken to reach maximum height of the flight and total height. When looking at a projectile you are trying to find the properties if it in the y and x components. Projectiles 1 have a parabolic trajectory and the component of the x value for the component for the y value are the same. In Projectiles 2 again there is a parabolic trajectory and everything on the right-hand side of the path is equal to the left hand side. In projectiles 3, the calculations are similar once...
