the speed of a body in a specific direction is the measure of velocity. rate of change in displacement with respect to time is known as velocity. velocity is a vector quantity that has both magnitude and direction. q2 what is speed? speed is measured as the ratio of distance to the ...
q3 what is velocity? velocity can be defined as the directional speed of a body in movement as an implication if the body’s rate of change in position is perceived from a particular point of reference and as calculated by a specific standard of time. example: 125km/h to the south. q4...
constantly colliding and changing their speed and direction, as the particles collide and change velocity, it is not practical to measure each velocity, and as there are particles moving in one direction equal to the particles moving in the opposite direction, they cancel out and the average velo...
Angular velocity is a vector quantity that expresses both direction and magnitude, while angular speed describes magnitude only. Angular speed defines how fast the central angle of a rotating body changes.
