Here's a breakdown:

* Gravity: A fundamental force of attraction between any two objects with mass. The more massive the objects, the stronger the gravitational pull. The closer the objects, the stronger the pull.

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

* Weight: The force of gravity acting on an object's mass. It's the force that pulls an object downwards towards the center of the Earth.

Calculating Weight:

We can calculate an object's weight using the following formula:

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

* g is approximately 9.8 m/s² on Earth. This value can vary slightly depending on location.

Example:

Let's say you have a mass of 60 kg. Your weight on Earth would be:

W = 60 kg x 9.8 m/s² = 588 N (Newtons)

Important Notes:

* Weight is a force, so it's measured in Newtons (N).

* Mass is a scalar quantity (just a number), while weight is a vector quantity (has both magnitude and direction).

* Weight can change depending on the gravitational field strength. For example, you would weigh less on the moon than on Earth because the moon has a weaker gravitational field.
