LabInApp is revolutionizing education sector by introducing 3D interactive platform which encompasses computer graphics and artificial intelligence. Attach the ring of spring balance A on a hook fixed in the wall and the spring balance B is attached to the hook of spring balance A. CBSE Class 8. Related Physics Topics for Tuition. During the experiment, he observed that a few air bubbles were sticking to the solid when immersed in water. In the class 11 Physics experiment given here, we will be learning how to find the spring constant of a spring by plotting a graph between the load and extension. Note the reading on the spring balance. A spring scale or spring balance or newton meter is a type of mechanical force gauge or weighing scale.It consists of a spring fixed at one end with a hook to attach an object at the other. Professor Mac is using a Newton spring balance in his experiments to illustrate Newton’s second law of motion. Friction.

Spring balance, weighing device that utilizes the relation between the applied load and the deformation of a spring.This relationship is usually linear; i.e., if the load is doubled, the deformation is doubled. Some spring balances are available in gram or kilogram markings and … A spring balance measures the weight of an object by opposing the force of gravity acting with force of an extending spring. To calibrate a spring balance in newtons . Lever – There are many possibilities with a meter rule as a lever with a load (known or unknown) suspended from a point near one end (say left), the lever itself pivoted on a knife-edge use slotted weights suspended from the other (right) side for effort. Range of the spring balance = 0 – 500 g = 0 – 5 N; Least count of the spring balance = 10 g; Mass of the wooden block with hook, R = 50 g; Value of ‘g’ = 9.8 … Bell Jar Experiment.
