An object starts linear motion with a velocity 'u' and under uniform acceleration 'a' it acquires a velocity v in time t'. Draw velocity time graph, from this graph obtain the following equations:
a) v =u + at
b) s = ut +at?

Answer:
An acceleration can cause speed to increase, decrease, and even stay the same! Acceleration tells you the rate at which the velocity is changing. ... The acceleration can change the magnitude and/or the direction of the velocity. Speed is only the magnitude of the velocity.
