Definition of spring scale
: a scale in which the weight indications depend upon the change of shape or of dimensions of an elastic body or system of such bodies.
What a spring scale is and how it is used?
A spring scale, sometimes called a spring balance, is a device used to measure the weight of an object. It hangs from above and consists of a spring with a hook at the bottom where you can attach an object. Notice that we said a spring scale measures the weight of an object, not its mass.
What is a spring scale used for kids?
A spring scale is a weighing scale used to measure weight or force, such as the force of gravity, the strength of a persons grip or the power of a vehicle. It consists of a spring fixed at one end with a hook to attach an object at the other.
What does a spring scale measure in units?
Spring scales are used to measure the force of a load. Spring scales measure the downward pull due to the Earth’s gravitational force of attraction and are measured in units called Newtons. Other spring scales measure grams (g). The gram scale measures the mass of objects.
How is spring balance used to measure weight?
Spring balances provide a method of mass measurement that is both simple and cheap. The mass is hung on the end of a spring and the deflection of the spring due to the downwards gravitational force on the mass is measured against a scale.
How does a scale work?
A scale displays weight by measuring a deflection; the springs are deformed by the load, and the force needed to deform the springs is measured, and converted into weight.
What does a scale measure?
Scales measure weight, which is the force acting on a mass that is equal to the object’s mass times its acceleration due to gravity. A scale can’t measure mass directly, because the weighing mechanism and the weight of any given object are dependent on local gravity.
What does the spring scale read?
The spring scale simply measures the tension, the magnitude of the force exerted by the string.
How do you make a spring scale?
Experimental Procedure
Hang the spring from a sturdily-mounted hook.Measure the length of the spring with no weight hanging from it. Hang a weight from the spring, and wait for it to settle.Again measure the length of the spring.Measure the mass of the weight, using the kitchen scale.
How do you calculate spring scale?
This law is expressed mathematically as F = kx, where F is force, x is the spring’s change in length and k is a number called the spring constant, which is different for springs of different sizes or materials. For a given spring, however, k remains the same as long as you stay within the spring’s elastic limit.
What is a balance used for in science?
balance, instrument for comparing the weights of two bodies, usually for scientific purposes, to determine the difference in mass (or weight).
