Answer 2

The Basic principle of measurement in physics.

• Measurement is the procedure of properly determining a quantity. It is inconceivable to get a precise understanding of a quantity without measuring.
• In fact, taking measurements of various quantities is a fundamental premise of physics. As a result, physics is known as Measurement Science. There are two approaches to learning about a quantity: qualitative and quantitative.
• Matter and energy characteristics may be perceived with our instincts and conveyed via words. This is the extent of our qualitative understanding of matter and energy.
• However, in terms of knowing these quantitatively, measurements are needed, and yardsticks are required for this measurement.
• To measure a physical amount, a convenient and fixed part or portion of it is utilized as a standard, and the quantity is measured with reference to that standard, and that fixed portion or part is used anywhere that fixed portion or part is utilised.
• The unit or yardstick of that quantity is the standard of measurement. When we say that a room is 20 metres long, we mean that a set length called a metre has been used as a standard, and the room is 20 times longer than that.
• Again, if we state that a body's mass is 10 kg, we're implying that a kilogramme has been used as a standard, and the body is 10 times heavier than the standard.
• As a result, the number of units discovered in a quantity will be the index of measurement for that amount, and two things are required to take measurement of a quantity. The first is a number, while the second is a unit. Without the other, one is worthless.
