Work is a key idea in physics that links force and distance in a simple way.
The main formula you should remember is:
Work = Force × Distance
This tells us that work happens when a force makes something move over a distance.
Let’s break it down into two main parts:
Force:
Distance:
When we talk about force and distance for calculating work, both need to happen in the same direction to get the right answer. For example, if you push a box to the right, both your push and the box's movement should go right. If the box moves up instead, your push needs to go up too for the work to be calculated properly.
It’s also important to know that work can be negative. This means the force is working against the movement. Think about pushing a heavy cart down a hill: gravity is doing positive work because it helps the cart go down. But if you try to pull it back up, you’re doing negative work because your force goes against the movement.
In real life, calculating work is very important because it helps us understand how energy moves from one place to another. For example, when you lift weights, your muscles exert force to lift them over a distance. This means you are doing work on the weights, which gives them potential energy.
In short, the link between force and distance is really important for figuring out work. This idea isn’t just for textbooks; it applies to everyday tasks like moving furniture and also to complex areas like engineering and physics.
