Displacement: - The modification in position of a body in a particular direction is called as displacement. It is a vector function and its unit in SI system is meter.
Distance: The actual length of path traversed by a body in a sub interval of time is known as distance. It is the actual path travelled by an object between its final and initial positions. It is a scalar function and its unit in SI is meter. Displacement can be positive, zero or negative but distance is always positive. If a particle goes in a straight line without modification in its direction, the value of displacement is same to the distance travelled. Otherwise it is usually less than it. Thus, Displacement distance
Ask questiA 1.10×10-2-kg bullet strikes a 0.300-kg block attached to a fixed horizontal spring whose spring constant is 2100 N/m and sets it into oscillation with an amplitude of 1
Coupling factor: If all the flux of a primary coil links with all the turns of a secondary then 100% coupling exists. Sometimes it is more convenient to use a coupling factor
Kirchoff"s Current Law states that in any electrical network, the algebraic sum of the currents meeting at a point (or junction) is zero, which means that the total current leavi
