Projectile Motion

 

In analyzing projectile motion two assumptions can be made: “(1)the free-fall acceleration g is constant over the range of motion and is directed downward, and (2) the effect of air resistance is negligible.”

Vectors are used to separate the motion into x and y components:

“Velocity in X direction = Velocity inital * cos(theta inital)”

“Velocity in Y direction = Velocity inital * sin(theta inital)”

These equations can be substituted into the equation position vector as a function of time:

“r final= r inital + v inital t + ½at^2”
