An intriguing and one of the most important topics for various government exams after 12th Science, Motion in a plane, which forms an integral part of the Physics syllabus for class 11, covers the basics of 2-d kinematics in a detailed way.This knowledge ensures a better understanding of the topics further up in Physics. Projectile motion is a form of motion in which an object or particle (called a projectile) is thrown with some initial velocity near the earth’s surface, and it moves along a curved path under the action of gravity alone. Its unit is in m/s2 and it is a vector quantity. 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°. It can also be defined as an object launched into the space and allowed to move free under the influence of gravity and air resistance. Consider the motion as the superposition of the motions in the x- and y-directions ! The word ballistics comes from the word ballista, which was a siege machine used for war during the late 18 th century. One component is along a horizontal direction without any acceleration (as no force acting in this direction) and the other along the vertical directionwith const… Centrifugal force is equal and opposite to centripetal force. Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. Basketball Physics. This acceleration is called centripetal acceleration. Centripetal acceleration is also called radial acceleration as it acts along radius of circle. Horizontal component of initial velocity = u cos θ. Vertical component of initial velocity = u sin θ. Horizontal component of velocity (u cos θ) remains same during the whole journey as no acceleration is acting horizontally. The path followed by the object is called its trajectory. Physicsbeckons.wordpress.com physicswithikgogia Page 1 Q1. PROJECTILE MOTION 1. PROJECTILE MOTION in Class XI. Motion of a stone in a circular path, tied with a string. Example: Parabolic water trajectory 5. asked Jan 16 in Physics by KumariMuskan (33.8k points) projectile motion; class-11; Circular motion is the movement of an object in a circular path. Projectile motion is a form of motion where an object moves in a parabolic path. It consists of a string OA whose upper end 0 is fixed and bob is tied at the other free end. 5> equation for the horizontal range of a projectile. Circular motion is the movement of an object in a circular path. 2> equation for time to reach maximum height. Characteristics of Projectile Motion: The direction and magnitude of the velocity of the body performing projectile motion change continuously. Vertical component of velocity (u sin θ) decreases gradually and becomes zero at highest point of the path. Under centrifugal force, body moves only along a straight line. When centripetal force is obtained from friction force as well as banking of roads, then maximum safe value of speed of vehicle.

If any object is thrown with velocity u, making an angle θ, from horizontal, then, Important Points & Formulae of Projectile Motion. At highest point, the linear momentum is mu cos θ and the kinetic energy is (1/2)m(u cos θ), The horizontal displacement of the projectile after t seconds, The vertical displacement of the projectile after t seconds, Kinetic energy at lowest point = (1/2) mu. A ball is projected with velocity 10 m/sec at angle of 30o with the horizontal surface. The motion of a projected object in flight is known as projectile motion which is a result of 2 separate simultaneously occurring components of motions. Vector Quantities :- Centrifugal force does not act on the body in an inertial frame but arises as pseudo forces in non-inertial frames and need to be considered. (i) Horizontal range is maximum when it is thrown at an angle of 45° from the horizontal. There will be total 10 MCQ in this test. The speed of the ball after 1 second will be (Use g=10m/sec2) a. where, v = the velocity of the vehicle and r = radius of the circular path.

CBSE Notes for Class 11 Physics Notes Biology Notes Maths Notes Chemistry Notes. Class – 11 Physics, Chapter – 6, Motion in a Plane Projectile Motion : Questions on this topics : 1 ) Define projectile or what do you mean by projectile? When the maximum range of projectile is R, then its maximum height is R/4. At highest point, the linear momentum is mu cos θ and the kinetic energy is (1/2)m(u cos θ), The horizontal displacement of the projectile after t seconds, The vertical displacement of the projectile after t seconds, Kinetic energy at lowest point = (1/2) mu. Angular velocity is a vector quantity and its unit is rad/s. The maximum height occurs when the projectile covers a horizontal distance equal to half of the horizontal range, i.e., R/2. (viii) A driver sees a child in front of him during driving a car, then it, better to apply brake suddenly rather than taking a sharp turn to avoid an accident. Projectile motion numerical problems class 11 Solution: Here we have to find out the value of vertical displacement y when horizontal displacement is x = 10 m. If value of y comes out to be less than height of wall then the projectile hits the wall otherwise not. Projectile motion is a predictable path traveled by an object that is influenced only by the initial launch speed, launch angle, and the acceleration due to gravity. Understand the motion for a projectile. The object is called a projectile, and its path is called its trajectory.The motion of falling objects, as covered in Problem-Solving Basics for One-Dimensional Kinematics, is a simple one-dimensional type of projectile motion in which there is no horizontal movement.
