Equilibrium means no net force is acting.An object can be in linear motion if the forces acting on it are balanced forces and due to this it is undergoing uniform linear motion.

The physical world is highly complex. It has vast orders of magnitude in respect of mass, length and time. Even then all the physical phenomena can be explained in terms of few basic principles of physics. That is, it is possible to comprehend nature in terms of few basic laws in spite of its vast complexities. This is what Einstein meant to say.

what do you mean by unit and dimensions?

Posted by Himanshu Sharma 5 years, 1 month ago

CBSE > Class 11 > Physics

1 answers

Yogita Ingle 5 years ago

Full names of the units, even when they are named after a scientist should not be written with a capital letter. Eg: Newton, watt, ampere, meter.

The unit should be written either in full or in agreed symbols only.
Units do not take the plural form. Eg: 10 kg but not 10 kgs, 20 w but not 20 ws.
No full stop or punctuation mark should be used within or at the end of symbols for units. Eg: 10 W but not 10 W.

Dimensions of a physical quantity are the powers to which the fundamental units are raised to obtain one unit of that quantity.
