Derive equations of motion?
First equation of motion:
Consider a body having initial velocity u,If it is subjected to an acceleration 'a' so that after time 't' its velocity becomes v.
By the definition of acceleration
acceleration=Change in velocity/time taken
Second equation of motion:
Suppose the distance travelled by the above body in time t=s
we have average velocity=(Initial velocity+Final velocity)/2
Third equation of motion:
