WebFeb 15, 2024 · V-T graphs in physics are a graphical representation of various types of motions ; it gives a quick description of the motion undertaken by the body/object of study. It is easier to study, formulate and therefore, is used to give quicker and simpler information about the state of a body. Based on the relative idea of rest and motion , the V-T ... WebNon-Uniform Speed: When a body covers unequal distances in equal intervals of time, then that body is said to be in non uniform speed. For e.g., an object thrown into air, like stone, moves at non-uniform speed, lift used to go up or down in a building. Non-Uniform Velocity: When the velocity is not uniform i.e. not constant.This implies that the velocity of the … WebDistance. Displacement. 1. Distance is the actual length of the path travelled by the particle in a given interval of time. Displacement is the shortest distance between the initial position and the final position of the moving particle in a particular direction. 2. Distance travelled by the particle in a given interval of time is always positive. lending club customer assistance
