Question

2. What does a spring balance measures. Explain its working with diagram and example

Answer 1

Spring balances are a natural sight in the classroom; they are normally used to quantify the force applied to an object. This force is generally estimated in Newtons and is basically the weight of an object. The weight of an object is an estimation of its mass x gravity (w=mg).

Spring balances are additionally now and again known as Newton-meters thus. Some spring balances are accessible in gram or kilogram markings and are utilized to quantify the mass of an object.

IT WORKS WITH THE HELP OF GRAVITY, I.E.  IT CALCULATES THE WEIGHT WHICH IS MASS*GRAVITY.IT ALSO CALCULATES THE FORCE OF FRICTION for e.g. WE TIE A BRICK TO THE SPRING BALANCE WITH THE HELP OF A STRING. THEN WE DARG IT ON A ROUGH SURFACE AND MEASURE THE READING WHICH APPEARS JUST BEFORE THE INITIAL MOVEMENT OF THE BRICK
