Here's the breakdown:
* Gravity: A force of attraction between any two objects with mass. The more massive the objects, the stronger the gravitational pull.
* Weight: The force of gravity acting on an object's mass.
To calculate weight, you use the following formula:
Weight (W) = Mass (m) × Acceleration due to gravity (g)
* Mass (m): The amount of matter in an object, measured in kilograms (kg).
* Acceleration due to gravity (g): The rate at which an object accelerates towards the center of the Earth due to gravity. This value is approximately 9.8 m/s².
Example:
Let's say you have a book with a mass of 1 kilogram (1 kg). To find its weight on Earth, you would multiply its mass by the acceleration due to gravity:
Weight (W) = 1 kg × 9.8 m/s² = 9.8 Newtons (N)
Therefore, the book would weigh approximately 9.8 Newtons on Earth.
