What would happen to your mass and weight if you were on the moon?
Your mass would be the same because the amount of matter is still the same but the weight will change because the gravitational pull is different. To be exact, your weight on the moon will be 1/6 of your weight on earth.

What is the difference between mass and weight? What are some similarities?
Full explanation that mass is the amount of matter in an object where weight is the gravitational pull on an object. Different equipment is used to measure the mass and weight. A similarity is that they both are physical properties of matter.
