  It's 6p.m, time to leave the railway station - Andy thought to himself, with a big sigh. Living a lonely life since the demise of his wife two years ago, everything to him seemed monotonous and tedious....

Moment of force is the idea to make a body to rotate on a pivot. Moment has a simple rule that is the closer you are to the pivot or the point the more energy you would require to rotate the body. This rule is obeyed by many objects which we use in our day-to-day life. Like a spanner handle is placed far from the pivot to rotate the nut or nail easier with less force. Similarly, in this case the pivot is the root of the tree, it is the turning point for the tree, when the crowd gathered they applied force very close to the pivot or the root this cause the tree not to budge but when Andy positioned the force on the far end from the pivot it made it easier for the crowd to move the tree. In simple, we can sum it up that the greater the distance the less the force needed and the smaller the distance the more force is needed which this scenario perfectly portrayed.  less

Momentum is the product of force and the perpendicular distance between the pivot and line of force. He considered providing a force greater than the weight of the tree, but this is only feasible if the force is delivered on the other side of the root.
    It is a fact that when a force is applied far from the pivot, the force is sufficient to elevate the other force/weight. Mr. Andy used that notion when assisting the individual.

The idea about moments is that the further a force acts away from the pivot(the turning point of an object), the more effective it will be in turning the object. For example, the knob of a door is situated the farthest from its pivot, the hinges. In the picture, we can see that the tree is tilted down towards the side of its roots. From this, we can guess that(counting the car as a pivot) there is a greater load acting downwards in that side of the tree, than the side with the leaves. The way the people were doing it before, they were wasting strength overcoming all the those forces and uprooting the tree. They were using the car as a pivot, and the distance between their force and the car/pivot was not much. However, pushing in an anticlockwise direction on the other side, with the leaves, shifts the pivot from being the car to being the roots, all the way on the other side of the tree. The pivot being far away, the forces proved effective.  less

As mentioned in the scenario, the roots of the tree were fixed with the ground so it was a fixed point and a fixed point is called a pivot. This pivot allowed the tree to be removed over the car. According to the principles of moment, the distance from the pivot to the point where the force is applied is directly proportional to the moment, meaning the longer this distance, the greater the rotation of the tree and that is why Mr Andy applied his force on the farther end of the tree so that with less force would produce greater moment due to the longer distance, away from the tree and was successful to remove it and save the passenger.  less

    Shaikh Nafisa Binte Fahad Andy told others to help lift the tree from the other side, as the force acting away from the root of the tree made it easier to lift the tree than near the root.

    The car was acting as a pivot here because the weight of the whole tree was on the car. The bottom side of the tree was not uprooted, so it was heavier than the upper part, so more force was needed to lift it from near the roots. Therefore, it was easier to lift the tree upwards at a certain distance away from the root of the tree as there was less weight in the upper direction.
    Today, we learned about a great example in the field of physics. this topic can be identified as the 'moments'. Moments are directly proportional to the force and distance of a body, just like this one! Easy-Peasy!  less
