physical quantities have numerical magnitude and unit
Practically all measurements are based on physics.
seven types of quantities may all physics measurements be expressed?
They are all measurements of some characteristic.
Pressure is not a change, it is a characteristic.
All that the samples do is enable the observer to make measurements of some characteristic.

All requires something to set it off, it needs vibration. :) that is from my physics teacher.
Measurements in physics are necessary to quantify and understand the behavior of physical properties. They provide a foundation for scientific analysis, experimentation, and comparison of results. Accurate measurements are crucial for verifying theories, predicting outcomes, and advancing our understanding of the natural world.
In physics, weight and mass are two distinct measurements. Mass is the amount of matter in an object, while weight is the force of gravity acting on that object.
In physics, "nm" stands for nanometer, which is a unit of length equal to one billionth of a meter. Nanometers are commonly used in scientific measurements to describe the size of molecules, atoms, and wavelengths of light. They are important in various fields such as nanotechnology, optics, and semiconductor physics for precise measurements at the atomic and molecular scale.
A physics lab is a designated space equipped with tools and equipment where experiments and investigations related to the principles of physics are conducted. It is where students and researchers can apply theoretical concepts, perform measurements, and gather data to better understand and analyze physical phenomena.
We all know that physics is a subject that includes computation. Without measurement we dont know distances, height, weight,length,and etc. We always used measurements, when we wake up we already using measurements because of the alarm clock that uses time.
