On Sunday, I truly learnt how to scrum.
You bend your legs, akin to compressing a spring (potential energy).
Then u engage, i.e release the spring (kinetic energy).
KAPOW!!! That's some power for you.
Try it.
But friends pls enter the correct hole. You must see where you are going so always look forward oright!!
Now some of us might then wonder... Isn't Potential energy (PE) related to a person's size? In fact, in school, we learnt:

PE=mgh
where
PE = Energy (in Joules)
m = mass (in kilograms)
g = gravitational acceleration of the earth (9.8 m/sec2)
h = height above earth's surface (in meters)
So is it having the fatter and taller people in your team means you will win the scrum?

Jr, you are on the path to enlightenment (save for the reference to the imparter of such knowledge).
The short answer to your question is NO – having stronger/taller people in your team does not mean that you will win those scrums.
Remember, its all about TECHNIQUE.
Experienced players are able to alter the height of the scrum by their ability to change the angle at knee. This can produce a significant disruption of the opposition scrum.
A prop can thus legally force her opponent to scrum lower, at a height she finds uncomfortable, and which is mechanically inefficient. When the opponent is pressurized she will normally do one of two things.
1. she can move her feet further back to relieve the discomfort. Eventually she may take her feet so far back she goes to ground flat on her face. Should this cause the scrum to collapse it is of course illegal. Even if she doesn't go to ground the position she is forced to adopt does not allow the maximum transmission of power through the scrum.
2. she will bend forward at the hip, her head gradually getting well below the line of the hip. This not only supremely uncomfortable it is illegal and could force a collapsed scrum.
In this context, a shorter, but equally strong prop will have a mechanical advantage over a taller one since she will naturally scrum at a height comfortable to her, whilst the taller prop will be forced to accommodate the additional height by disadvantageous angles at knee and / or hip.
Building a Scrum by Graham Smith
Scrummaging requires concentration, discipline and co-ordination. A dominant scrum not only provides your team with excellent possession, but it is also a vehicle which can exhaust the opposition pack and dispirit the opposition backs, for they will always be on the back foot, always under pressure.
Remember these lessons well young one and nirvana will be yours.
Ruck on.
jus to add on to wat's written above.. for scrums, beside body posture, binding and techniques, a huge part of it depends on how the forward pack works together as pack.. timing is the other key issue.. this is very important in 15s as it's a 8 men scrum..
in 15s scrum, the forwards need to know how to work as a pack and u need a game plan to screw up the oppo's scrum when in defence.. how are u going to destroy the oppo's scrum.. when and where to wheel, when to thrust and drive, when to pull back, when and how to split the oppo's scrum into two, how to let the oppo's front rowers dance in the air, how to let the oppo's front row kiss the grass with u pinning on top of them, how to make the oppo's loose head prop out of the scrum, how to torture the oppo's hooker that they dread going into a scrum with u, how to hold back the oppo flankers so that they cant breakaway fast, how to frustrate the front rowers to commit mistakes and loose their cool... and that's on defensive scrum... but bear in mind, watever u can do to the oppo, they can do to u as well.. so prepare to give and take.. it's part of the game...
tune in again for theory on offensive scrums...
