Question

Which is a result of using a machine?

A. The amount of work that is done is increased.
B. The work input is less than the work output.
C. Both the force and the distance through which it acts increase.
D. The distance through which a force acts increases, and the force decreases.

Answer 1

Using a machine increases the amount of work that is done.

Step-by-step explanation:

The correct answer is A. The amount of work that is done is increased. When a machine is used, it allows us to do work with less force, but the distance over which the force is applied increases. As a result, the work done is increased. For example, using a lever allows us to lift heavy objects with less force, but we need to move the lever through a longer distance to do so.However, it's important to note that the effectiveness of a machine depends on various factors, including its design, maintenance, and the specific task it is intended to perform. Additionally, the integration of machines into various industries and processes may also have implications for employment and require considerations for ethical and social impacts.
