If a spring balance with the iron ball is released what reading does the spring balance record and why
Answers
Answer:0
Explanation:when a spring balance is with iron ball is released then the spring balance will 0 weight because it is a free fall as gravity is acting on it.
Answer:
Concept:
A Spring balancer only shows reading when it's one end is hold or hanged on a rigid fixed point because the object hanged on spring balancer with a spring is attracted downwards due to gravity so the spring stretches which led to increase in no. of units in spring balancer but during a free fall the end which is to be attached on surface or to be hold is not fixed, so the spring did not stretched it simply falls which led to no increase in unit of spring balancer. So the spring balancer shows 0.
Explanation:
A spring balance measures the weight of an object by opposing the force of gravity acting with the force of an extending spring. May be used to determine mass as well as weight by recalibrating the scale. It works by Hooke's Law, which states that the force needed to extend a spring is proportional to the distance that spring is extended from its rest position.

• Some spring balances are available in gram or kilogram markings and are used to measure the mass of an object.
• Spring balances consist of a cylindrical tube with a spring inside. One end (at the top) is fixed to an adjuster which can be used to calibrate the device. The other end is attached to a hook on which you can hang masses etc.
When the forces are acting in opposite directions, but are not equal, we say that the net force is greater than 0 N. There is a resultant force. If the forces are equal and acting in the same direction there will also be a resultant force.
