Second Equation of Motion

Second equation of motion Derivation

Suppose a body is moving with initial velocity “Vi” after time t its velocity becomes Vf. The distance covered by the body is “S”.The acceleration of the body is represented by a.
Explanation:
second equation of motion
Consider the speed-time graph in which the initial velocity “Vi” of the body is represented by “OA”.After a time interval, OC the speed of the body changes uniformly and becomes “Vf” which is represented by line BC in the graph.
The slope of the graph¬†is AB which is the acceleration¬†“a”.
The distance travelled by the speed time graph is calculated as:

This is the second equation of motion, which shows the relationship of distance, initial velocity, time and acceleration.
