Question

define tension in a string compare the motion of two object bodies in case of both moving vertically over a frictionless pulley ​

Answer 1

Answer:

If a person is holding a block of weight W attached to the end of a string, a force is experienced by him .   This force is known as Tension. When the body is at rest, the magnitude of tension is equal to the weight   of the body suspended by the string. Tension and the weight acts in the opposite direction. Tension is   vector quantity, which has both magnitude and direction. Its magnitude remains constant at all points of   the string.
