Here's a breakdown:
* Gravity: A fundamental force 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:
Weight (W) = Mass (m) x Acceleration due to gravity (g)
* g: The acceleration due to gravity is approximately 9.8 m/s² on Earth's surface.
Important Note:
* Weight is a force, and is measured in units of Newtons (N).
* Mass is a property of an object and is measured in units of kilograms (kg).
Example:
A person with a mass of 70 kg on Earth would have a weight of approximately:
W = 70 kg x 9.8 m/s² = 686 N
