Supreme Basic Physics Formulas And Units

Here are some basic physics formulas for competitive exams-.

Basic physics formulas and units. Basic Physics Formulas - Part I The average speed is the average of speed of a moving body for the overall distance that it has covered. So we have created awesome list of formulas of physics. Speed is the distance moved per unit Speed distance time assuming constant seed.

The dimension of a physical quantity are the powers to which the fundamental or base quantities like mass length and time etc. Strain Strain is defined as the extension per unit length due to an applied stress. The unit of force is Newton.

Also includes the value of Physical constants. Physics Terms Definitions and Units page 4 Stress Stress is the force per unit cross-sectional area when equal opposing forces act on a body. This article provides a comprehensive physics formulas list that will act as a ready reference when you are solving physics problems.

Consider the physical quantity Force. If Q is the unit of a derived quantity represented by Q M a L b T c then M a L b T c is called dimensional formula and the exponents a b and c are called the dimensions. Planck constant h 663 10 34 Js 4136 10-15 eVs.

Have to be raised to represent the quantity. PE eV ½mv 2 1V 1JC 1NC 1Vm 1J 1 Nm 1 CV.

It is used to calculate the average speed S of a moving body for the distance covered D as well as the time duration T. Physical Constants Speed of light c 3 108 ms Planck constant h 663 1034 J s hc 1242 eV-nm Gravitation constant G 667 1011 m3 kg1 s2 Boltzmann constant k 138 1023 JK Molar gas constant. But is students understand the concepts behind the formulas properly they can enjoy learning the subject.
