In recent days many have had the fun of trying to educate MV on the effects of gravity. His main
argument is thus:
Bikes with shock absorbers weigh more and hence cause more damage to trails.
Anyone with a mere basic understanding of physics will say this is absolutely wrong. Some people
with a little more physics knowledge (Mike himself) will say this is true. Whilst those with a firm
understanding of physics will say its laughably incorrect.
Here's why:
Acceleration due to gravity is 9.8 m/s/s we all know this..There are slight variations in this
numerical value (to the second decimal place) which are dependent primarily upon altitude.
Mike argues that since "force (f)= mass (m) x acceleration (a)" a larger mass will create more
force. This is true in itself, its obvious.
However mike then says that the acceleration (a) is gravity. This is where he has shown no
understanding of advanced physics.
If we let him have the fact that (a) is indeed gravity we all know that acceleration due to gravity
is constant regardless of mass. In other words a bike and a hiker both will accelerate at the same
speed due to gravity when in a free fall situation.
Therefore it can be seen that mike is very confused with regards to physics and has a tendency to
change his argument when cornered.
Its all good fun and yes the above is verifiable should anyone require it.
Simon.........I like mike, he makes me look good. We should market him as an accessory.
