Linear Motion also called rectilinear motion is a one-dimensional motion along a straight line, and can, therefore, be described mathematically using only one dimension. The linear motion can be of two...
It is defined as the angle between resultant current and voltage in AC circuit. it is represented by COS PHI In case of a pure resistor, the angle between the voltage and current is equal to zero hence...
This is the foremost important physics topic. Students very often than not forget Conversion of Units of physical quantities to one system while solving numerical questions. This leads to wrong answers...
Dot or Scalar Product of Vectors Dot Product of two vectors A and B is defines as product of magnitude of the vectors and cosine of the angle between them. A•B = |A||B|CosT, Where T is the angle...
