What is the advantage in using a simple machine?
Reduces the amount of work needed to move on object
Increase the mechanical advantage by increasing the effort force that is applied
Reduce the amount of energy required
Reduce the work needed to effort force applied rotion

The advantage in using a simple machine is to reduce the amount of work needed to move on object

Option A

Explanation:

A Simple machine is a device with less moving parts used to change motion and force to perform work. Some of the simple machines are the inclined plane, lever, wedge, wheel and axle, pulley, and screw which we all use in our daily life.

These simple machines make our work fast and accurate and also does not require much effort for the work to be done. In other words, we can tell simple machines make our work simpler. For eg: If we take the simple machine wheel and axle, in a bicycle, instead of moving the whole wheel, if we apply force on the pedals, the wheel starts moving. Thus, only less effort is required to move an object.
