Detailed explanation-1: -Solutions. W=mg, where g is the acceleration due to gravity and m is the mass of an object.
Detailed explanation-2: -Weight refers to the force with which gravity pulls upon the object.
Detailed explanation-3: -w=mg. Since g = 9.80 m/s2 on Earth, the weight of a 1.00-kg object on Earth is 9.80 N: w=mg=(1.00kg)(9.80m/s2)=9.80N. When the net external force on an object is its weight, we say that it is in free fall, that is, the only force acting on the object is gravity.
Detailed explanation-4: -Weight is the force acting on an object due to gravity-it has the unit newtons (N) and acts towards the centre of a gravitational field. The weight of an object can be measured using a spring-balance often called a force meter calibrated in newtons and sometimes called a newton meter.
Detailed explanation-5: -Which statement describes the direction of gravitational force? It is always attractive. What is the significance of a positive sign for the electrostatic force? It indicates a repulsive force between two like charges.
