Final answer:
The weight of an object is influenced by its location due to variations in gravitational pull, its mass, altitude, and other minor factors such as temperature and speed. While mass remains constant, weight can vary significantly on other celestial bodies or at different altitudes on Earth.
Step-by-step explanation:
The factors that affect the weight of an object are its location on Earth, its mass, altitude, and to a lesser extent, factors such as temperature and speed. It is important to note that while mass is a measure of the amount of matter in an object and remains constant regardless of location, weight is the measure of the gravitational force acting on that mass. The weight of an object will vary depending on the strength of the gravitational pull at that location, which can be significantly different on other celestial bodies like the moon. For instance, an object on the moon would weigh roughly one-sixth of its weight on Earth due to the weaker gravitational force.
At different locations on Earth, the weight can vary slightly because the gravitational field is not uniform; it is slightly stronger at the poles than at the equator. Also, higher altitudes can lead to a lower weight as the gravitational pull decreases with distance from the Earth's center.
