Question

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.


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.
