Vernier callipers is an instrument which measures the dimensions of an object correct to 0.1 mm. It can measure both the inner and outer diameters of a tube.

The force existing between two charges when separated by a certain distance is studied by Coulomb’s Law.

Moment means the turning capability. Thus, moment of a force is the turning capability of the force. For a body to turn it should be pivoted at a point. Turning force is also called torque. It is the product of the applied force and the shortest distance between the force and the pivot point. Its unit is newton meter.
