Answer:
Mass remains constant but weight reduces
Explanation:
Mass is the amount of matter in an object so whether on moon or any other planet, it does not change despite the changes in acceleration.
Weight is a product of mass and acceleration due to gravity, expressed as W=mg where m is the mass, W is weight and g is acceleration. From the above formula, it is evident that when you decrease g, then W also decreases while m is constant. Similarly, when m is constant and g is increased then W also increases.
Therefore, for this case, since g decreases, the weight decreases but mass remains constant.
Answer:
B. The weight of the brick could be less than 5lbs on the Moon.
Explanation: No matter what mass CANNOT change whether on the moon, running, or doing whatever. However, due to lack of gravitational pull on the moon: you can have a different weight.
