At highest point, the velocity of the body is u cos θ in horizontal direction and the angle between the velocity and acceleration is 90°. v The approach will be to formulate integral expressions that can be evaluated numerically. Projectile motion is a form of motion experienced by an object or particle (a projectile) that is projected near the Earth's surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are passive and assumed to be negligible). − Q Unit vector notation (part 2) Projectile motion with ordered set notation. 2 v In this case, the position has the general formula. and The path that the object follows is called its trajectory. x , this means that the drag force becomes quadratic in v when the product of speed and diameter is more than about v tan x x From the horizontal displacement the maximum distance of projectile: The total horizontal distance (d) traveled.

Vertical velocity after t seconds, vy = (- u sin θ) + gt 0 μ , with an initial velocity 0.015 a y This is the principle of compound motion established by Galileo in 1638,[1] and used by him to prove the parabolic form of projectile motion.[2].
