Yes, weight is the gravitational attraction force between an object and Earth.
An expanded response to your question
Yes, weight is indeed the gravitational attraction force between an object and Earth. This fundamental concept is an essential aspect of physics and explains why objects fall towards the ground when released.
To delve deeper into this topic, let’s consider Sir Isaac Newton’s law of universal gravitation. He famously proclaimed, “Every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.”
This law provides the framework for understanding how objects interact gravitationally. When it comes to weight, we can apply this law to explain why we experience a force acting upon us when on Earth.
Here are some interesting facts related to weight and gravity:
- Weight is a measure of the force of gravity acting on an object. It is commonly measured in units of newtons.
- Weight is not the same as mass. Mass refers to the amount of matter in an object, while weight depends on the mass and the gravitational force.
- The acceleration due to Earth’s gravity is approximately 9.8 meters per second squared (9.8 m/s²). This value varies slightly depending on location and altitude.
- Weight is directly proportional to an object’s mass. If the mass of an object doubles, its weight will also double.
- Weight can vary depending on the gravitational field. For instance, an object on the Moon would weigh approximately one-sixth of what it weighs on Earth due to the Moon’s weaker gravity.
- The force of gravity attracts all objects towards the center of the Earth. This force is what gives weight to objects on the planet’s surface.
- Weightlessness occurs when an object or a person experiences an absence of the sensation of weight, such as during freefall or in space where gravitational forces are negligible.
- The concept of weight extends beyond Earth. Every celestial body exerts a gravitational force on objects near it, determining their weights relative to their masses.
To further illustrate the relationship between weight and mass, here’s a table showcasing different masses and their corresponding weights on Earth:
| Mass (kg) | Weight (N) |
|---|---|
| 10 | 98 |
| 50 | 490 |
| 100 | 980 |
| 500 | 4,900 |
| 1000 | 9,800 |
In conclusion, weight is indeed the gravitational attraction force between an object and Earth. Understanding this concept allows us to comprehend the fundamental nature of gravity and its impact on our world. As Sir Isaac Newton’s law of universal gravitation aptly states, every particle of matter experiences this force of attraction with an intensity that depends on mass and distance.

Additional responses to your query
Weight is the force generated by the gravitational attraction of the earth on any object. Weight is fundamentally different from the aerodynamic forces, lift and drag. Aerodynamic forces are mechanical forces and the object has to be in physical contact with the air which generates the force.
The weight of an object is the gravitational force between the object and the Earth. The weight of an object depends upon its mass and the gravitational field strength.
The force of attraction between you and the Earth is your weight.
Weight is normally determined when you step on a scale, depress the springs in that scale, and take a measurement off of a dial of some sort. When you step on the scale, you are pushing on it due to the force of gravitational attraction between you and the earth.
But any object with mass exerts a gravitational force on all other objects with mass. For example, there is a gravitational force between you and every object around you! The gravitational force between two objects is larger when the masses of the objects are larger.
Newton’s law of universal gravitation states that everybody of nonzero mass attracts every other object in the universe. This attractive force is called gravity. It exists between all objects, even though it may seem ridiculous.
