What is Gravitational force? Give gravitational units of force.
Earth exerts a force of attraction on each object. This force is due to gravity and its magnitude is directly proportional to the mass of the object. This force is known as gravitational force and its units are gravitational units.
In MKS system the gravitational unit of force is kilogramme force i.e., kgf. In CGS system it is gramme force, gf.
