Two trains are traveling down a track. Train A has more mass than Train B. What will happen when the two trains attempt to stop with the same force at the Train Station? A:The train with the smaller mass will require less time to stop than the train with the larger mass. B:The train with the larger mass will require less time to stop than the train with the smaller mass. C: The train with the smaller mass will take longer to stop than the train with the larger mass. D: The train with the larger mass will have less inertia than the train with the smaller mass.​

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
