Which force accounts for the difference between mass and weight?
a
Gravitational force
b
Frictional force
c
Magnetic force
d
Air resistance force
a) Gravitational force accounts for the difference between mass and weight.
The correct answer is a) Gravitational force. The force of gravity is responsible for the difference between mass and weight. Mass is an intrinsic property of an object and is the measure of the amount of matter in an object, while weight is the force of gravity acting on an object's mass. Weight can vary depending on the strength of the gravitational force, whereas mass remains constant regardless of the gravitational field.
The force that accounts for the difference between mass and weight is the gravitational force. To understand this, let's break down the question and explain each term.
Mass: Mass refers to the amount of matter in an object and is measured in kilograms (kg). It is an intrinsic property of an object and is constant anywhere in the universe.
Weight: Weight, on the other hand, refers to the force exerted on an object due to gravity. It is the measure of the gravitational force acting on an object and is measured in newtons (N). Weight varies depending on the strength of the gravitational field.
Gravitational Force: The force of gravity is what pulls objects towards the Earth (or any other celestial body with mass). It is the force that gives objects weight. The formula to calculate gravitational force is F = mg, where F represents the gravitational force, m is the mass of the object, and g is the acceleration due to gravity.
So, the force that accounts for the difference between mass and weight is the gravitational force (option a).
