What is "Triangle rule of addition" ?
What is " triangle rule of addition " ? If a particle is given two velocities simultaneously its resultant effect velocity is different from the two velocities and is obtained by using a special rule I.e " Tr iangle rule of addition " Suppose a small ball is moving inside a long tube at a speed of 3 m/s and the tube itself is moving in the room at a speed of 4 m/s along a direction perpendicular to its length. In which direction and how fast is the ball moving as seen from the room ? Above figure shows position of tube and the ball. By pythagorean we conclude that resultant velocity is 5 m/s. General rule for finding the resultant of two velocities may stated as follows :- Draw a line AB representing first velocity with B as the head. Draw another line BC representing second velocity with its tail B coinciding with the head of the first line. The line AC with A as the tail and C as the head represents the resultant velocity. Above figu...
