I can assure you that A-Level physics is not easy but it is definitely worth the time if you put the effort in and practise all those equations!
a joint effort means something that is tried together as a group
So they can do things more with less effort. Do things faster and easier. Tractor is the product of laws of physics. The phones to communicate. Radios, TVs for weather forecasts. So many physics in agriculture.

In physics not really; in physiology, sure -- you measure the heat per unit time.
