Readers ask: What Is The Definition Of Weight In Physics?

Weight, gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon.

What is the basic definition of weight?

noun. a measure of the heaviness of an object; the amount anything weighs. physics the vertical force experienced by a mass as a result of gravitation. It equals the mass of the body multiplied by the acceleration of free fall.

What is weight short answer?

Weight (symbolized w ) is a quantity representing the force exerted on a particle or object by an acceleration field, particularly the gravitational field of the Earth at the surface. At the Earth’s surface, a kilogram mass weighs about 2.2 pounds, for example.

What is the definition of weight in matter?

In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the force exerted on an object by gravity.

What is the formula for weight in physics?

The general formula to find the weight is given as, W = mg (N/kg). Here ‘g’ represents the acceleration due to gravity. On the earth, the value of g is 9.8 m/s2. It is also known as the gravitational constant.

What is weight an example of?

Others define weight as a scalar quantity, the magnitude of the gravitational force. Yet others define it as the magnitude of the reaction force exerted on a body by mechanisms that counteract the effects of gravity: the weight is the quantity that is measured by, for example, a spring scale.

What is an example word of weight?

See word origin. Frequency: Weight is how heavy something is or how much mass it has. An example of weight is when a person is 100 pounds. noun.

What is the definition of weight ABCD?

The force by which a body gets attracted towards the centre of the Earth is called its weight. The SI unit of weight is Kg.

How can I calculate weight?


  1. Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth.
  2. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.

What is weight class 9?

The weight of a body is the force with which it is attracted towards the centre of the earth. The force of attraction of earth on a body is called as weight. W=m*g. S.I. unit of weight is Newton or kg m/s2. Weight of 1 kg mass is 9.8 Newton.

What is difference mass and weight?

Mass is a measure of how much force it will take to change that path. Mass depends on how much matter – atoms and so on – there is in an object; more mass means more inertia, as there is more to get moving. Weight, on the other hand, is a measure of the amount of downwards force that gravity exerts on an object.

What is the weight in science?

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. Weight is measured in newtons.

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.

What is area formula?

The most basic area formula is the formula for the area of a rectangle. Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).

What’s the work formula?

To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd. If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.

What is normal force formula?

In this simple case of an object sitting on a horizontal surface, the normal force will be equal to the force of gravity F n = m g F_n=mg Fn=mgF, start subscript, n, end subscript, equals, m, g.
