Question

Which of the following are not ways that a machine can make work easier?

A) Increasing the force applied
B) Changing the direction of the force
C) Reducing the distance over which the force is applied
D) Increasing the amount of work done

Answer 1

A machine can make work easier by reducing the amount of force required, but it does not change the amount of work done.

Step-by-step explanation:

Each simple machine has its specific purpose, and many complex machines are combinations of these basic elements. Simple machines provide mechanical advantages, allowing humans to accomplish tasks more easily by reducing the amount of force required or changing the direction of the force. Understanding the principles of simple machines is fundamental to mechanics and engineering.

A machine can make work easier by reducing the amount of force required to do the work. However, it does not change the amount of work done. The correct option from the given choices is D) Increasing the amount of work done.
