The measure of the pull of gravity on an object is commonly referred to as weight. Weight is a force experienced by an object due to the gravitational attraction between that object and a larger body, such as a planet or a star.
Weight is directly proportional to the mass of the object and the strength of the gravitational field it is in. The formula to calculate weight is:
Weight = mass * gravitational acceleration
The gravitational acceleration, denoted by 'g', represents the strength of the gravitational field and varies depending on the celestial body and its location. On Earth, the average value of gravitational acceleration is approximately 9.8 meters per second squared (m/s²).
It's important to distinguish weight from mass. Mass is a measure of the amount of matter in an object and remains the same regardless of the gravitational field it is in. Weight, on the other hand, depends on both the mass of the object and the strength of the gravitational field, and it can vary on different celestial bodies due to differences in their gravitational fields.
