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
Reflection of a Pulse at a Free End Let's assume a pulse moving by a medium - perhaps by a rope or a slinky. What happens to the pulse while it reaches the end of in which medi
A parallel plate capacitor is made from 25 plates, each 70mmby 120mm interleaved with mica of relative permittivity 5. If the capacitance of the capacitor is 3000pF verify the
Suppose a baseball rolls 3.2 m across the floor. If the ball's angular displacement is 82 rad, what is the circumference of the ball?
An equiconvex lens has the radius of one curved surface is 0.12 m and focal length of 0.10 m. Determine the refractive index of the material of the convex lens.
When two objects A and B are in thermal equilibrium with a third object (C) independently, then they (i.e. A and B) are in thermal equilibrium equally i.e. Therefore, the t
A windmill is operating in a 10 m/s wind that has a density of 1.2 kg/m 3 . The diameter of the windmill is 4 m. The constant-pressure (atmospheric) stream tube has a diameter of 3
