Measuring Instruments For Length And Mass

When we measure the distance between any two points in terms of width thickness depth and height we measure length.

Measuring instruments for length and mass.

The use of the word measure in the sense of a measuring instrument only survives in the phrase tape measure an instrument that can be used to measure but cannot be used to draw straight lines. Measuring tapes come in two varieties. Stop watches are also used to measure time in some sports. Several tools and methods exist for measuring mass.

In general there are three most measured magnitudes in the world of physics for high school level namely length mass and time and dimension. One type is made of cloth or plastic. Determining mass means determining the amount of matter in an object of interest. This unit differed from place to place and trade to trade.

Length and mass introduction source. Those quantities which can be measured is known as physical quantities like length mass etc. This is used by those needing a flexible instrument with which to measure length such as a tailor or anyone measuring the circumference of an object. In this video we will learn how to take measurements of length using a meter stick volume using a graduated cylinder and mass using a digital scale.

As can be seen in the photographs on this page a two metre carpenter s rule can be folded down to a length of only 20 centimetres to easily fit in a. Inch is the measure of the thumb which was used to measure the length of items small for example the seam of a cloth length of paper etc. For its part an inch was traditionally the width of an average thumb but edward ii of england ruled in the 14th century. Foot is the measure of length typically defined as 15 3 of the height of a human body with an average height of 160 cm.

A measuring instrument is a tool used to measure a magnitude or dimension in physics. These include balances scales newtonian based measurement devices measurement transducers vibrating tube mass sensors and the use of gravitational interaction. In the past a common time measuring instrument was the sundial today the usual measuring instruments for time are clocks and watches for highly accurate measurement of time an atomic clock is used. The most natural way to measure length is to compare it to some part of the body and for centuries people did just that the unit we call a foot has been used since ancient times.

It is equal to the length of an average foot formerly 11 1 42 inches but now 12 inches. All the substances around us can be measured by using various units like the mass of gold length of clothes the quantity of milk etc. The standard instruments used nowadays to measure a length are ruler meter scale measuring tape vernier caliper and screw gauge. Standard international si unit for measurement of length is meter.
