1) The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg.

The pulling force that acts along a stretched flexible connector, such as a rope or cable, is called tension. When a rope supports the weight of an object that is at rest, the tension in the rope is equal to the weight of the object: T = mg.

2) It measures weight by hanging objects from the spring scale hook. Measures material, such as sand, by pouring it into a plastic bag and hanging the bag . Dual scales measure from 0-1000 grams or up to 10 Newtons.

3) A spring balance measures the weight of an object by opposing the force of gravity acting with the force of an extended spring. It is used when the accuracy afforded by other types of scales can be sacrificed for simplicity, cheapness etc.

hope it helps.....
