In one-dimensional kinematics, a particle can move strictly along a straight line. The description of motion of the particle can be done in two ways: (i) mathematical equation and (ii) graphs. The choice of a particular method for solving a problem often depends upon the type and nature of problem, for example the graphical method provides more physical insight One dimensional motion is categorised into 1. motion with constant velocity 2. motion with constant acceleration, and 3. accelerated and de-accelerated motion If you represent inotion (1) by the graph on position time and velocity-time coordinates, the graphs may look like as given below. One very interesting case comes up, when a particle is thrown at a certain angle from the horizontal, the particle travels in the medium along a curved path, known as parabola. - The trajectory of the parabola written in the mathematical equation is given by y=xtantheta-(1)/(2)(gx^(2))/((v_0costheta))^(2) Ineglect resistance of medium and its motion where Vs and are the initial velocity of the projectile and the projection angle at the point of projection measured with the + x axis. There are some applications which we have seen in our life, like in many game shows, the theory of the projectile is always used An air gun is aimed at an elevated target, which is released in a free fall by some mechanism as the bullet leaves the nozzle. Irrespective of falling speed of object, the bullet will always hit the target. QOut of the two methods, graphical method and mathematical equation, which gives you the better precision
