How force is related to weight?

In the trading of goods, weight is taken to mean the same as mass and is measured in kilograms. Scientifically, however, it is normal to state that the weight of a body is the gravitational force acting on it and hence it should be measured in newtons (N), and that this force depends on the local force due to gravity.

What is the relationship between force and weight of an object?

Weight is a measure of the force of gravity acting on an object. According to Newton’s laws of motion, force is directly proportional to both mass and acceleration, and the equation for force is F = m * a, where m = mass and a = acceleration. We can use this equation to solve for weight.

How does the force of gravity relate to weight?

That is, the weight of an object is determined by the pull of gravity on it. Thus, an object’s physical weight may change from place to place: if a body weighs 54 kg on Earth, its weight will be just over 9 kg on the Moon, since the Earth’s gravitational force is six times stronger than the Moon’s.

Why is weight in kg?

Since there is no practical easy way to measure mass, in everyday life we use the kilogram as a unit of weight assuming that the gravitational field is fairly constant around earth. However scales have to be calibrated locally to compensate the slight gravitational field variation in different places.

How are weight and mass forces related to each other?

A force causes an object to undergo a specific change. Unbalanced forces cause changes in speed, shape or direction. Gravitational forces act between masses. Friction opposes motion. Weight is not the same as mass. Mass is a measure of how much matter is in an object. Weight is a force acting on that matter.

Why is the weight of an object considered a force?

The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.

What does the term weight mean in physics?

Weight is a force acting on that matter. Mass resists any change in the motion of objects. In physics, the term weight has a specific meaning – which is the force that acts on a mass due to gravity.

How is the weight of a 10 kilogram mass related to the force?

A 10-kilogram mass is sitting on a table. There are two equal, opposing forces — the mass presses down on the table, and the table presses up on the mass. The static gravitational force, the “weight”, is proportional to: (1) \\displaystyle f = mg. Where: f = Force, newtons. m = Mass, kilograms.
