Here's a breakdown:
* Gravity: A fundamental force of nature that attracts any two objects with mass. The Earth has a large mass, so it exerts a strong gravitational pull on objects near its surface.
* Weight: The force of gravity acting on an object's mass. It's measured in units of force, like Newtons (N).
Formula for weight:
Weight (W) = Mass (m) × Acceleration due to gravity (g)
* Mass: The amount of matter in an object (measured in kilograms).
* Acceleration due to gravity (g): The acceleration experienced by an object falling freely near the Earth's surface. It's approximately 9.8 m/s².
Example:
If an object has a mass of 5 kilograms, its weight on Earth would be:
W = 5 kg × 9.8 m/s² = 49 N
