Why is a spring balance a Newton meter?
Answer 1: A Newton meter is just any device that measures force (it’s called a “Newton meter” because a “Newton” is a unit of force). A spring balance is a device that measures force by measuring how much a string stretches when a force is applied to it. So, a spring balance is actually a type of Newton meter.
What is the formula for spring balance?
It is calculated by dividing the change of force by the change in spring extension. For the example in the figure below, this is calculated by dividing 5 newtons by 50 mm, which gives a spring constant for this Newton spring balance of 0.1 newtons per mm extension.
What is spring balance used for?
Main uses of spring balances are to weigh heavy loads such as trucks, storage silos, and material carried on a conveyor belt. They are also common in science education as basic accelerators. They are used when the accuracy afforded by other types of scales can be sacrificed for simplicity, cheapness, and robustness.
What is spring balance answer?
Spring balance is a mechanical device used for measuring the weight or force of an object by opposing the force of gravity with the force of an extended spring.
What is the reading shown in spring balance?
Then reading is 40N.
Why does a spring balance show wrong measure after long use?
Why ? This is because of continuous usage, the wire loses its elasticity and does not regain it original dimension.
What is the reading of the spring balance on the rough surface?
Answer: reading of spring balance indicates that the force of friction has decreased.
What are two things you should do before and after you use a balance?
In order to protect the balances and ensure accurate results, a number of rules should be followed:
- Always check that the balance is level before using it.
- Never weigh directly on the balance pan.
- Never add chemicals to a container or piece of weighing paper while it is on the balance.
- Do not weigh hot or cold objects.
Why do you use weighing paper whenever you use a balance?
Weighing paper is often used when weighing solid, powdery substances on an analytical balance. By preventing the substance from making contact with unwanted materials, the precision of the measurement may be increased.
Why do we use Weighing by difference?
Weighing by difference is a way to weigh materials accurately. The weight of the material is the difference between the two weights of the vial before and after you transfer the material from the vial.
