We know that your mass, or the amount of matter in your body, does not change if your travel to other planets. Your weight, however, is affected by the pull of gravity. Calculate the weight of a 35-kg dog travelling the solar system. This is just another way we can use Newton’s second law: force = mass acceleration. The force of gravity (i. e., weight) equals the mass of the object times the acceleration due to gravity on that planet. pls help lol, I'm struggling
