Optimal Angle For A Projectile Part 1 Mp4 Youtube You want a projectile to fly as far as possible, at which angle should you launch it? we'll start with formulas for the initial velocity. This video complements the lecture notes published at xmphysics a level physics learning resourcescreated by mr chua kah hean ( xmphysics ).
Optimal Angle For A Projectile Part 1 Components Of Initial Velocity This physics problem, determining the launch angle that gives the maximum range when the starting point is above the level ground, is a personal favorite sin. I feel tempted to give a bit of a twist to this question. as john rennie mentions in a comment above, unless you are talking about slowly moving microscopic projectiles, drag forces are best modeled as being proportional to the square of the velocity. Mathematically, the horizontal distance that a projectile covers follows the formula (v^2)sin(2theta) g (simple proof). if v and g are kept constant, distance would be maximum if sine has the max value i.e. 1. so if sin(2theta)=1, then theta=45 degrees. With this four part installment from internet pedagogical superstar salman khan's series of free math tutorials, you'll learn how to find the optimal angle at which to launch a projectile. (1) part 1 of 4 how to calculate the optimal angle for a projectile, (2) part 2 of 4 how to calculate the optimal angle for a projectile, (3) part 3 of 4.

The x axis is divided into quadrants (0, 90, 180, 270, 360). notice in the graph that sin(x) rises from 0 to 1 as x rises from 0 to 90 degrees. then, it drops from 1 back to 0 as x rises from 90 to 180 degrees. refer back to the double angle \(sin(2\theta)\) in the original formula up top. The angle of reach is the angle the object must be launched at in order to achieve a specific distance: \(\mathrm{θ=\dfrac{1}{2} \sin ^{−1}(\dfrac{gd}{v^2})}\). objects that are projected from and land on the same horizontal surface will have a path symmetric about a vertical line through a point at the maximum height of the projectile.
