However, the angle between the velocity and acceleration is 90 degree. The velocity of the body at the highest point is u cos Θ in the horizontal direction. The vertical component of velocity (u sin Θ) gradually decrease and at the highest point of the path becomes 0. The horizontal component of velocity (u cos Θ) remains the same during the whole journey as herein, no acceleration is acting horizontally. If any object is thrown with the velocity u, making an angle Θ from horizontal, then the horizontal component of initial velocity = u cos Θ and the vertical component of initial velocity = u sin Θ. The velocity at any time “ t “ during the motion.The maximum height reached during the motion.The time is taken to reach point A from O.For this particular case, we will calculate the following: In the above diagram, where a particle is projected at an angle θ, with an initial velocity u. The motion of such a particle is called Projectile Motion. When a particle is projected obliquely near the earth’s surface, it moves simultaneously in the direction of horizontal and vertical. The motion of the earth around the sun.The motion of a billiard ball on the billiard table.The motion of a projectile is considered as a result:įew Examples of Two – Dimensional Projectiles It is an example of projectile motion (a special case of motion in a plane). The above diagram represents the motion of an object under the influence of gravity. Projectile motion is calculated by a way of neglecting air resistance in order to simplify the calculations. Addition and Subtraction of Vectors – Graphical Method.Resolution of Vectors and Vector Addition.The projectile motion is always in the form of a parabola which is represented as: Browse more Topics under Motion In A Plane The projectile motion consists of two parts – one is the horizontal motion of no acceleration and the other vertical motion of constant acceleration due to gravity. Some examples of Projectile Motion are Football, A baseball, A cricket ball, or any other object. Equations of motion, therefore, can be applied separately in X-axis and Y-axis to find the unknown parameters. In a projectile motion, the only acceleration acting is in the vertical direction which is acceleration due to gravity (g). Projectile refers to an object that is in flight after being thrown or projected.
