weight, gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon. … Alternatively, weight is the product of an object’s mass and either the gravitational field or the acceleration of gravity at the point where the object is located.

## Is weight an attractive force?

The weight-force or weight of an object is the force because of gravity, which acts on the object attracting it towards the centre of the earth.

## Is weight a force of attraction between all objects?

Weight is a force that acts at all times on all objects near Earth. The Earth pulls on all objects with a force of gravity downward toward the center of the Earth.

## What force is a force of attraction?

A force of attraction is any type of force that causes objects to come together, even if those objects are not close to or touching each other. The first force that causes attraction is the gravitational force. … The second force that can cause attraction is the electric force, also known as the electrostatic force.

## Is mass a force of attraction?

Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.

## Is weight a contact force?

A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar non-contact force is gravity, which confers weight. In contrast a contact force is a force which acts on an object coming physically in contact with it.

## Why is weight a force?

Weight is the result of gravity . The gravitational field strength of Earth is 10 N/kg (ten newtons per kilogram). This means an object with a mass of 1 kg would be attracted towards the centre of Earth by a force of 10 N. We feel forces like this as weight.

## Is weight a force True or false?

Weight is the force due to gravity and is calculated using Newton’s Law of Gravitation. Weight = mass x gravitational field strength of the planet. Mass is the amount of matter in an object. … Weight does not depend on whether the object is compressed or spread out.

## What are Isaac Newton’s 3 Laws called?

The Newton’s three laws of motion are Law of Inertia, Law of Mass and Acceleration, and the Third Law of Motion. A body at rest persists in its state of rest, and a body in motion remains in constant motion along a straight line unless acted upon by an external force.

## How does weight relate to the gravitational force of attraction?

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.

## What is an example of attractive force?

There are numerous attractive forces prevailing in nature. Some of them are magnetic force, electric force, electrostatic force and gravitational force. Gravitational force is very well-identified instance force of attraction as it draws objects towards itself regardless of its distance.

## What is meant by force of attraction?

a force between two bodies, molecules, particles, or the like, that attracts each to the other. … Gravity is the force of attraction between two bodies that have mass.

## What are the 2 types of forces of attraction?

There are two kinds of forces, or attractions, that operate in a molecule—intramolecular and intermolecular.

## Is weight greater than mass?

Usually, the relationship between mass and weight on Earth is highly proportional; objects that are a hundred times more massive than a one-liter bottle of soda almost always weigh a hundred times more—approximately 1,000 newtons, which is the weight one would expect on Earth from an object with a mass slightly greater …

## Are gravitons real?

There is no complete quantum field theory of gravitons due to an outstanding mathematical problem with renormalization in general relativity. In string theory, believed to be a consistent theory of quantum gravity, the graviton is a massless state of a fundamental string.

## How do you find the force of attraction?

The mathematical formula for gravitational force is F=GMmr2 F = G Mm r 2 where G is the gravitational constant.
