Learn what is a moment in physics, including how to measure the turning effect of a force and the role of the pivot in everyday examples like a spanner.

## Understanding what is a moment in physics If you have ever opened a door or used a pair of scissors, you have already applied the principles of moments. A moment is simply the turning effect of a force around a fixed point, which we call the pivot. Whether you are balancing on a seesaw or using a spanner to loosen a bolt, the physics remains the same. In this video, we break down the fundamental components of rotation:
* Identify common real world examples like hinges and seesaws.
* Understand why we measure moments in Newton metres.
* Learn how the size of the force changes the total turning effect.
* See why the distance from the pivot is just as important as the force itself. The magnitude of a moment depends on two specific factors. First is the amount of force you apply. Second is the distance from the pivot to the point where that force is applied. This is why it is much easier to open a heavy door if you push near the handle rather than near the hinge. By increasing the distance, you increase the moment without needing to push any harder. Understanding how force and distance interact is the first step toward mastering basic mechanics and engineering.
