1. Mass is a property of a physical body and it is also given as a measure of resistance to acceleration for a body when a net force is applied. In simple words, mass is essentially "how much stuff" is in an object. Kilogram is the SI unit of m...
What is the SI unit for stress and strain? What is the unit for potential difference? Which is not a correct SI unit? Why? a) ms-1 b) kg c) g d) kmh-2 How to do conversions? Suppose you have an equation E = mc^2 where the units of E are kg m^2/s^2 and the units ...
The SI unit of acceleration is m/s2. When measuring acceleration, one is measuring the change in an object's speed over a specified amount of time... Learn more about this topic: Acceleration | Definition, Formula & Examples from Chapter...
To set the stage, we look at how pressure is measured. Like a lot of physical quantities, pressure comes in many units. Pascals**,**measured as kilograms per meter per second squared in base units or Newtons per square meter, are an SI unit of pressure – a metr...
Other definitions of Physics states, "It is the study of natural science that studies the related entities of force and energy, motion and behavior of an object through space and time, matter and its fundamental constituents." In simple words, it can be said that physics is one of the most...
Force is not an absolute fundamental like the other three - rather, it is derived from the result of the actions caused on a body by the values of the other three fundamentals. The unit of force in the International System of Units is the Newton. The unit of force in the English ...
Molecules of plastics, for example, can be made of hundreds or even thousands of individual atoms joined together in incredibly long chains called polymers. Polythene (also called polyethene or polyethylene) is a very simple example of this. It's a polymer made by repeating a basic unit ...
The SI unit of inductance is Henry abbreviated as 'H'. Here students will find a detailed explanation about the inductance units (SI Unit and Other Inductance Units). Visit to know more.
speed is a measure of distance traveled over a certain amount of time. Speed is often described simply as the distance traveled per unit of time. It is how fast an object is moving.
