Answer:
Derivation of First Equation of Motion by Graphical Method
The first equation of motion can be derived using a velocity-time graph for a moving object with an initial velocity of u, final velocity v, and acceleration a. In the above graph, The velocity of the body changes from A to B in time t at a uniform rate.
Question-
Derive the first equation of motion.
Answer-
Assuming that a body started with initial velocity “u” and after time t it acquires final velocity v due to uniform acceleration a.
We know acceleration is defined as the rate of change of velocity, also which is given by the slope of the velocity-time graph.
Thus both from definition as well as graph Acceleration = Change in velocity/Time Taken i.e. a = v-u /t or at = v-u
Therefore, we have: v = u + at
