The longer handle gives you more leverage.
You use Force to push or pull an object in an attempt to make it move.
When you want to cause something to rotate (tighten or loosen a nut for example), you need Torque.
Torque = the force you apply to your spanner times the distance your hand is from the nut you are trying to turn.
Thus, if you have a longer spanner, you can place your hand farther from the nut and the Torque on the nut will increase.
You have to be careful about long handled wrenches or slipping a piece of pipe over a wrench to make it longer as you can generate so much Torque that you can snap the bolt clean off or strip the threads.
If you have to tighten a nut/bolt very firmly, but don't want to strip/snap it, you can use a Torque Wrench. It has a gauge that tells you how much Torque you are applying to the nut/bolt so that you can tighten it to specifications without going over.

Why is a wrench a second class lever?
In a second class lever the fulcrum and input effort are at opposite ends with the object load between.Though with a wrench to fasten a nut/bolt you apply effort at one end and this turns the load , which to my understanding is the nut/bolt you're trying to fasten at the other end.The fulcrum is the jaw used to grip the nut/bolt and turn over and the nut/bolt is the object load.How is the load between?
What needs to be true for a wrench to reduce the force needed to tighten a bolt?
The wrench needs to have a longer handle to increase leverage. This allows the force applied to be spread over a greater distance, making it easier to tighten the bolt. Additionally, the wrench should be the correct size to match the bolt to ensure an effective grip.
How do you use an adjustable wrench?
You adjust the width as close as possible to the flats of the bolt yo are working with, fit the wrench on and turn. Keep the wrench gripping the flats as much as possible.
