When Projectile Projected Upward at an Angle with Horizontal Time of flight can be obtained from the equation,ģ. Initial velocity in vertical direction = u sin θ Initial velocity in horizontal direction = u cos θ When Projectile Projected Downward at an Angle with Horizontal If velocity makes an angle φ, from horizontal, thenĢ. Initial velocity in vertical direction = 0 When Projectile is Projected Horizontally (ii) For angle of projections and (90° – 0) the horizontal range is same.ġ.

(i) Horizontal range is maximum when it is thrown at an angle of 45° from the horizontal Horizontal range It is defined as the maximum distance covered in horizontal distance. Maximum height It is defined as the maximum vertical distance covered by projectile. Time of flight It is defined as the total time for which the projectile remains in air. When the maximum range of projectile is R, then its maximum height is R/4.The maximum height occurs when the projectile covers a horizontal distance equal to half of the horizontal range, i.e., R/2.In case of angular projection, the angle between velocity and acceleration varies from 0° Angular momentum of projectile = mu cos θ x h, where h denotes the height.Acceleration of projectile is constant throughout the motion and it acts vertically downwards being equal to g.Kinetic energy at lowest point = (1/2) mu 2.The vertical displacement of the projectile after t seconds.The horizontal displacement of the projectile after t seconds.At highest point, the linear momentum is mu cos θ and the kinetic energy is (1/2)m(u cos θ) 2.Important Points & Formulae of Projectile Motion At highest point, the velocity of the body is u cos θ in horizontal direction and the angle between the velocity and acceleration is 90°.Vertical component of velocity (u sin θ) decreases gradually and becomes zero at highest point of the path.Horizontal component of velocity (u cos θ) remains same during the whole journey as no acceleration is acting horizontally.Vertical component of initial velocity = u sin θ.Horizontal component of initial velocity = u cos θ.If any object is thrown with velocity u, making an angle θ, from horizontal, then When any object is thrown from horizontal at an angle θ except 90°, then the path followed by it is called trajectory, the object is called projectile and its motion is called projectile motion. So, go ahead and check the Important Notes for Class 11 Physics Projectile Motion and Circular Motion from this article.

With the help of Notes, candidates can plan their Strategy for particular weaker section of the subject and study hard. Candidates who are pursuing in Class 11 are advised to revise the notes from this post.
