In physics, the tension on a suspended object said to be equal to the weight of the object plus or minus the mass of the object times the acceleration acting on it. In other words, this is the weight of the object plus or minus the force on it, depending on the direction in which the force is acting.
Tension is the force of pulling which acts on a body. One example of tension is the force felt by the string when a body is suspended from it in air. In this case, the acceleration is equal to the acceleration due to gravity.
