But when we throw it at an angle, then it travels for a distance and then falls down. This path followed by the object seems to be like a parabola. This part is not linear not circular, this is called projectile motion, and the path followed by the object is called a trajectory. Throwing a ball or anything: When we throw any object up into the sky we see that it eventually comes down. How long does he take to cross a river 1.0 km wide if the river flows steadily at 3.Now let us discuss each one of the projectile motion examples in detail: Question: A man can swim at a speed of 4.0 km/h in still water.

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 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.
