Derive the second equation of motion with the help of speed time graph. What are the measuring instruments?
Answers
Answer:
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:
second equation of motion derivation
This is the second equation of motion, which shows the relationship of distance, initial velocity, time and acceleration.
