Final answer:
To calculate your weight on the Sun, which has 28 times more gravity than Earth, multiply your Earth weight by 28. The gravitational acceleration on the Sun is significantly greater than on Earth.
Step-by-step explanation:
If the Sun has 28 times more gravity than Earth, the acceleration due to gravity can be calculated using Newton's law of universal gravitation.
Your weight on the Sun would be your Earth weight multiplied by the gravity ratio of the Sun to Earth. The gravity on the surface of the Sun, gSun, is approximately 274 m/s2, much more than Earth's 9.8 m/s2. So, if you weigh W on Earth, your weight on the Sun would be W multiplied by (gSun / gEarth) = W * (274 / 9.8) = 28W.
Therefore, the equation to find your weight on the Sun,
WSun, given your weight on Earth, WEarth, is WSun = WEarth * 28.
