I'm grateful to Tim for highlighting this sloppy phraseology, which I will endeavour to avoid in future. You're quite right Tim, it is a silly thing to say.

hehe, sorry Chris.

I am willing to accept that, as soul surfer points out, that it lazy shortening and will be impossible to iradicate. I still do maintain that gravity is not a force, though will not be so snobby as to criticise people for alikening gravity to a force.

Sorry Tim, but I can't resist giving you a dose of your own medicine, but you've spelled ERADICATE incorrectly.

Everyone, I'm starting a new discussion topic in which we scrutinise all Tim's posts for spelling mistakes... ;)

Hmmm yes, it appears as though you're right. Indeed, when trying to write ERADICATE I did wonder whether I had spelt it correctly. To avoid further embarrassment, I have put this through a spellchecking thing so I can use big words/phrases, such as “chiropody” and “Public Expenditure Review”, if I so wish.
I never was good at English. Oh well…never mind…:(

GRAVITY IS NOT A FORCE
« Reply #29 on: 14/05/2009 15:37:27 »
As I understand it rate of relative motion can only be changed by the application of a force  thus f=ma   (force = mass times acceleration)
so when a mass accelerates it is due to a force acting upon it.
In the case of objects falling to earth that force is due to gravity
thus the correct term should be "Acceleration due to gravity" rather than
force of gravity - or am I talking bollocks again?

When the force is also proportional to the mass (i.e. M1 M 2G/rsquared) then the acceleration is all that counts.
m/secondsquared is the equivalent to newtons /kg .
Not "bollocks", I think.
