What is the projectile. Give example. Prove that path followed by a
Projectile Fired horizontally is parabolic?
Answers
Answer:
Projectile is an object projected with some velocity and its initial direction of motion makes an angle α ( α >0 and α <90°) with horizontal direction. Projetile moves in a two dimensional plane so that at given time it has vertical displacement as well as horizontal displacement Thus we conclude that the trajectory of the projectile is of parabolic nature. However while doing the derivation we have taken certain assumptions like there is no air resistance and the value of acceleration due to gravity is uniform for the entire path (i.e. the projectile does not go too high from ground).
Answer:
Motion of a particle in a gravitational field is called Projectile Motion. It may be the gravitational field of any planet. When a particle is projected at an angle x{0<x<=90}. Then it is said to be in Projectile Motion.
Explanation:
When a particle is projected with a speed v with an angle x wrt horizontal. Then the velocity has two components along vertical and horizontal which a re independent of each other. So there is a motion in two. Plane v(y)=vsinx ;v(x)=vcosx
Writing the displacement along both planes will give you a relation that's going to be a parabola. Hope it helps :)
