Here's a breakdown:

* Gravity: A fundamental force of nature that attracts objects with mass towards each other. The more massive an object, the stronger its gravitational pull.

* Mass: A measure of the amount of matter in an object.

* Weight: The force of gravity acting on an object's mass.

Formula for Weight:

Weight (W) = Mass (m) x Acceleration due to gravity (g)

* g is approximately 9.8 m/s² on Earth's surface.

Example:

If an object has a mass of 10 kg, its weight on Earth would be:

W = 10 kg x 9.8 m/s² = 98 Newtons (N)

Key Points:

* Weight is a force, measured in Newtons (N).

* Mass is a property of an object, measured in kilograms (kg).

* Weight depends on the strength of the gravitational field, which varies depending on location.

* The higher the mass of an object, the greater its weight.

* The stronger the gravitational field, the greater the weight of an object.
