Final answer:
To find your weight on Mars, calculate your mass using Earth's gravity and then multiply by Mars's gravity. Your weight will be less on Mars than on Earth due to the lower gravitational pull. The exact weight on Mars can be calculated step by step using the gravitational constant and the known gravities of Earth and Mars.
Step-by-step explanation:
To calculate how much you would weigh on Mars, we can use the concept of gravitational force. Your weight on Earth is the force exerted on you by Earth's gravity, which can be calculated using Newton's law of universal gravitation, F = Gm1m2/r2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between the centers of the two masses. On Mars, the acceleration due to gravity is 3.71 m/s2. Your mass is the same everywhere, but your weight changes depending on the local gravity.7
To find how much you would weigh on Mars, we first need to find your mass from your weight on Earth. Since gravitational acceleration on Earth is 9.81 m/s2, we can calculate your mass as follows:
- Calculate your mass on Earth: Mass = Weight / Earth's gravity = 111 lbs / 9.81 m/s2.
- Convert your mass to kilograms: 111 lbs * 0.453592 kg/lb.
- Calculate your weight on Mars by multiplying your mass by Mars' gravity: WeightMars = Mass * 3.71 m/s2.
By using this process, we can find that your weight on Mars would be less than on Earth.
