As you move further away from the Earth's surface, the pull of gravity decreases, resulting in a decrease in weight. This is because the Earth's mass is concentrated at its center, so the farther away an object is from the center, the less gravitational force it experiences.
Yes, the formula is W = mg, where W is weight, m is mass, and g is the acceleration due to gravity. However, this formula assumes that the object is located on the Earth's surface. To calculate weight at different heights, the formula can be modified to include the distance from the Earth's center.
The change in weight at different heights can have significant effects on human health, especially for individuals who live at high altitudes. The decrease in gravitational force can lead to a decrease in bone density and muscle mass, which can increase the risk of osteoporosis and other health issues.
Yes, weight changes at different heights on other planets due to their varying masses and sizes. For example, on Mars, the gravitational force is about 38% of that on Earth, so a person would weigh less on Mars than they do on Earth at the same height.
Technically, there is no limit to how high an object can be and still have weight, as long as it is within the gravitational pull of a massive object. However, as an object moves further away from these massive objects, the gravitational force decreases and the weight becomes negligible.
