Question

All the relation between speed velocity anad acceleraiotns

Answer 1

speed is a scalar quantity which means containing only magnitude with no distance
it is related to distance
speed =distance / time

velocity is a vector quantity means having both magnitude and direction
it is related to displacement i.e. the shortest distance
velocity is distance travelled in unit time
velocity=displacement/ time

both of the units of speed and velocity are :m/s

acceleration is the rate of change of velocity
acceleration=(v-u)/t where v is the final velocity and u is the initial velocity
unit of acceleration is m/s²
