Question

Write the mathematical expression and so unit of speed,average speed,velocity,average velocity and acceleration

Answer 1

Speed-speed of a body as the distance travelled by it in unit time or speed is tge rate of change of distance
formula-speed=distance travelled by /time taken
velocity-velocity is the rate of change of displacement
formula-velocity=change in displacement/time taken
acceleration -is the rate of change of velocity
formula-acceleration =change in velocity /time taken
= final velocity -initial velocity /time taken
