What statements about weight are correct?
A
Weight depends on the gravitational pull o
B
Weight is the same as mass
C
It is a type of force (N)
D
weight = mass x gravitational acceleration
Explanation: 

Detailed explanation-1: -Mass times gravitational acceleration is weight. 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.

Detailed explanation-2: -To calculate the weight, use the following general formula: W = mg. Here, “W” is the weight of the object, “m” is the mass of the object, and “g” is the acceleration due to gravity. On Earth, the value of g is 9.8 m / s2.

Detailed explanation-3: -Mass of a body is the amount of matter present in the body whereas weight is the magnitude of gravitational force acting on the body.

Detailed explanation-4: -Mass is a scalar quantity and weight is a vector quantity whereas weight of an object is the force of gravity acting on it. Therefore mass is a scalar quantity and weight is a vector quantity.

Detailed explanation-5: -FAQ on Mass and Weight Answer 1: weight helps in finding the mass of a body based on the Formula of Mass that states, ‘ mass is equal to weight when divided by the acceleration of Gravity. Hence we can say M= W+G. The acceleration of Gravity on Earth is 9.8 meters per Second sq and mass is measured in Newton.
