Answer 1

Answer: A machine can help a person to reduce the force required to change the $a_0$ to $a_1$ .

Explanation: If we want to shift the position of a heavy object like a plant stem then lots of force is required and for this many people might be required to generate the force. But if we use a lever(machine) then less man power will be required as the lever reduces the required force and helps to shift the position of the object.

So, a machine can help a person to reduce the force required to change the $a_0$ to $a_1$ .
