What is the first equation of motion |
| Answer» The final velocity (v) of a moving object with uniform acceleration (a) after time, t.Let, the initial velocity = u.Final velocity = v.Time = tAcceleration = aWe know that, Acceleration (a) =Change in velocity/Time taken⇒a = (Final velocity-Initial velocity)/Time taken⇒ a = (v − u)/t⇒ at = v − u⇒ at − v = −u⇒ −v = −u − at⇒ v = u + at ---(i)This equation is known as first equation of motion.\xa0 | |
