ACCELERATION SI UNIT IS M/S2 AND VELOCITY M/S. HOW AND WHY

Asked by 27th May 2008, 2:36 PM
Answered by Expert
Answer:

Velocity of a body is the distance travelled by it per unit time in a given direction. SI unit of distance is metre (m) and of time is second (s); hence the SI unit of velocity is meter per second (m/s)

Acceleration of a body is defined as the rate of change of its velocity with time. SI unit of velocity is metre per second (m/s) and of time is second (s); hence the SI unit of acceleration is metre per second square (m/s2)
