| Video Discription | simple harmonic motion class 10 | mass attached to spring class 10 | 10th class physics chapter 10 A body is said to be vibrating if it moves back and forth or to and fro about a point. Another term for vibration is oscillation. A special kind of vibratory or oscillatory motion is called the simple harmonic motion (SHM), which is the main focus of this chapter. We will discuss important characteristics of SHM and systems executing SHM. We will also introduce different types of waves and will demonstrate their properties with the help of ripple tank. 10.1 SIMPLE HARMONIC MOTION (SHM) In the following sections we will discuss simple harmonic motion of different systems. The motion of mass attached to a spring on a horizontal frictionless surface, the motion of a ball placed in a bowl and the motion of a bob attached to a string are examples of SHM. MOTION OF MASS ATTACHED TO A SPRING One of the simplest types of oscillatory motion is that of horizontal mass-spring system (Fig.10.1). If the spring is stretched or compressed through a small displacement x from its mean position, it exerts a force F on the mass. According to Hooke’s law this force is directly proportional to the change in length x of the spring i.e., ........ (10.1) where x is the displacement of the mass from its mean position O, and k is a constant called the spring constant defined as The value of k is a measure of the stiffness of the spring. Stiff springs have large value of k and soft springs have small value of k. It means that the acceleration of a mass attached to a spring is directly proportional to its displacement from the mean position. Hence, the horizontal motion of a mass-spring system is an example of simple harmonic motion.

(10.2) The negative sign in Eq. 10.1 means that the force exerted by the spring is always directed opposite to the displacement of the mass. Because the spring force always acts towards the mean position, it is sometimes called a restoring force. A restoring force always pushes or pulls the object performing oscillatory motion towards the mean position. Initially the mass m is at rest in position O and the mean resultant force on the mass is zero (Fig.10.1-a). Suppose the mass is pulled through a distance x up to extreme position A and then released (Fig.10.1-b). The restoring force exerted by the spring on the mass will pull it towards the position O. Due to the restoring force mean the mass moves back, towards the mean position O. The magnitude of the restoring force decreases with the distance from the mean position and becomes zero at O. However, the mass gains speed as it moves towards the mean position and its speed becomes maximum at O. Due to inertia the mass does not stop at the mean position O but continues its related searches 1. simple harmonic motion class 10 2. simple harmonic motion class 11 3. simple harmonic motion physics 4. simple harmonic motion in urdu 5. simple harmonic motion bsc 1st year 6. simple harmonic motion and waves 7. simple harmonic motion a level physics 8. simple harmonic motion and waves class 10 9. simple harmonic motion animation 10. simple harmonic motion and waves chapter 10 11. a level simple harmonic motion 12. simple harmonic motion by pgc 13. simple harmonic motion bsc 2nd year 14. simple harmonic motion class 11 physics 15. simple harmonic motion class 11 pgc 16. simple harmonic motion class 10 urdu medium 17. simple harmonic motion derivation 18. simple harmonic motion definition in urdu 19. simple harmonic motion example 20. simple harmonic motion experiment 21. simple harmonic motion explanation 22. simple harmonic motion equation derivation 23. simple harmonic motion equations 24. simple harmonic motion explained 25. simple harmonic motion in mechanics 26. simple harmonic motion jee 27. simple harmonic motion jee mains 28. simple harmonic motion jee mains one shot 29. simple harmonic motion jee advanced 30. simple harmonic motion jee questions 31. simple harmonic motion jee mains questions 32. simple harmonic motion jee sprint 33. simple harmonic motion kya hai 34. simple harmonic motion kya hota hai 35. simple harmonic motion lecture in urdu 36. simple harmonic motion lecture 1 37. simple harmonic motion physics class 10 38. simple harmonic motion physics class 11 39. simple harmonic motion time period 40. simple harmonic motion urdu #shm #SHM #10thphysics #atifahmedofficial #atifahmadofficial #simpleHarmonicMotion #massAttachedToSpring #urdu #hindi #class10 #10thPhysics #physics #physics10th #10thClassPhysics #physicsClass10 #physics10th #metricPart2 #class10Physics #10classPhysics |
