Overview
Weight is the force of gravity acting on an object's mass. While your mass remains the same anywhere in the universe, your weight changes depending on the local gravitational field.
💡
Pro Tips
Weight (W) = Mass (m) × Gravity (g).
Gravity on Earth is approx 9.81 m/s².
In physics, weight is measured in Newtons (N), not kilograms.

Fun Facts
"On the Moon, you would weigh only about 1/6th of what you weigh on Earth."
"If you could stand on Jupiter, you would weigh more than twice as much as on Earth."
"An object in free-fall is 'weightless' because no support force is acting on it, even though gravity is still present."
