What is a 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. A spring balance measures the weight of an object by opposing the force of gravity acting with the force of an extended spring.
What is spring balance for Class 8?
Spring balance is a device used for measuring the force acting on an object. It consists of a coiled spring which gets stretched when a force is applied to it. Stretching of the spring is measured by a pointer moving on a graduated scale. The reading on the scale gives the magnitude of the force.
How do you calculate spring balance?
The reading of the spring balance is the pulling force on it divided by the acceleration due to gravity $g$.
Which balance is more sensitive?
A physical balance is more sensitive than a beam balance as it can accurately measure even.
Does spring balance measure pressure?
Spring balance is used for measuring : (1) The force acting on an object (2) The force of friction (3) Magnitude of the pressure (4) Relative motion between the object. Answer: Spring balance is used to determine the force acting on the object (weight). Spring balance works on the principle of Hooke’s law.
What is a spring balance Class 9?
A spring balance measures the weight of an object by opposing the force of gravity acting with the force of an extending spring. 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.
What is spring balance Class 11?
A spring balance consists of a spring fixed at one end with a hook to attach an object at the other. Remember, a spring balance cannot measure mass, only weight.
What is range of spring balance?
Spring balances with weight range from 5 up to 1000 grams have a gripping device for the loading while the ones with weight range from 2,5 up to 50 kg have a load hook. Mechanical spring balances are unique for demonstrations.
What is the formula for spring force?
The spring force formula is expressed through the equation: F = – kx.
Is physical balance is sensitive than beam balance?
Answer: It is true. as it can accurately measure even a very small mass, even milligram.
Is physical balance more sensitive?
What is meter stick?
Metersticks are usually divided with lines for each millimeter (1000 per meter) and numerical markings per centimeter (100 per meter), with numbers either in centi- or millimeter. Yardsticks are most often marked with a scale in inches, but sometimes also feature marks for foot increments.
