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
a balloon is filled with 100 kg of helium, and that the velocity is 2.0 m / s what is the external kinetic energy?
It is the energy possessed by a body because of the interactive forces inside the object. This may be defined as the work done in assembling all the particles of a body in a exact
