Newton’S Second Law Of Motion Apparatus

For Demonstrating The Newtons Second Law Of Motion. Comprises A Spring Loaded Steel Launcher Mounted In Brackets On A Metal Base. Also Includes A Pair Of Steel Spheres, One Solid And Other Holed To Slide It Into The Launcher. Complete With A Rod Mounted On The Base For Fixing The Apparatus On A Suitable Retort Stand. Spring Compressed By The Handle Can Be Locked Into Two Different Positions Corresponding To Two Potential Energy Levels. Once Spring Is Compressed, Both The Spheres Can Be Located At Their Respective Places. On Releasing The Handle, The Launcher Imparts Horizontal Velocity To The Solid Sphere While The Other Sphere Simply Falls Vertically. Falling Of Both The Spheres On The Ground Implies That Vertical And Horizontal Velocities Are Independent. (Newton’S Second Law Of Motion Apparatus)
