question #3 as the mass of an object decreases, its gravity will decrease stay the same be half the original saved increase question #4 which type of surface would have the least friction? saved smooth bumpy uneven rough

Answer

Brief Explanations:

For Question #3, the gravitational force an object exerts is directly proportional to its mass. So as mass decreases, gravity decreases. For Question #4, friction is caused by the irregularities between two surfaces. A smooth surface has fewer irregularities, resulting in less friction.

Answer:

Question #3: A. Decrease Question #4: A. Smooth
