You may have realized that it takes effort to push an object. Even small objects require a little bit of effort, and it is easy to imagine how hard it is to push around something large, like a car. Using what you know from your own experience, as well as what you learned about force and motion in class, correctly finish the statements below.

Question

A. Using a smaller force on a given object will result in
B. Using the same force but reducaing the mass of an object results in
C. If you maintain a constant force, and the object starts speeding up, then it
D. If you maintain a constant force, and the object starts slowing down, then it

1. faster motion
2. slower motion
3. has lost some of its mass
4. has gained some mass

Answer 1

Here are the correct completions for the statements based on your understanding of force and motion:

A. Using a smaller force on a given object will result in 2. slower motion.
B. Using the same force but reducing the mass of an object results in 1. faster motion.
C. If you maintain a constant force, and the object starts speeding up, then it 3. has lost some of its mass.
D. If you maintain a constant force, and the object starts slowing down, then it 4. has gained some mass.

However, it's worth noting that the last two statements (C and D) aren't typically accurate in the context of classical mechanics as described by Newton's laws of motion. Mass is generally constant; the change in speed (acceleration or deceleration) is a result of the net forces acting on the object rather than a change in mass. A more appropriate completion for C would be that the object is experiencing a net force in the direction of motion, while for D, it would indicate that there's a net force acting opposite to the direction of motion.

So, the correct answers for statements C and D should be better evaluated in a classical mechanics context without implying mass changes.
