10/10 - sorry ;)

Re: how smart are you -- physics
 

Why apologise? :shrug: You should be pleased.

bof/nerd/swot - no one likes a smart ar$e ;)

7/10 for me. Some of them were guesses though.

Re: how smart are you -- physics
 

5/10 for me. this is one subject I hated with a passion at school

Re: how smart are you -- physics
 

10/10 - I actually did well at something :)

Re: how smart are you -- physics
 

IIRC mass is constant, weight isn't. Weight is amongst other things dependent on latitude. Something to do with the force of gravity being slightly different on different latitudes I believe. Mass does not 'suffer' this variation. I'm sure someone will correct me if I'm wrong.

Re: how smart are you -- physics
 

kg is MASS, Newtons is weight, which is the same as force.

Think about it, you multiply a mass in kg by an acceleration in ms^-2, the unit of the weight isn't going to be in kg is it?

Re: how smart are you -- physics
 

mass is resistance to translational acceleration, and is indeed constant.
weight is the gravitational force resulting on a mass...

i.e. if your mass is 100 Kg, you will weigh 1000N on earth but only about 166N on the moon.

10/10 But what has wiring a plug got to do with physics?

Re: how smart are you -- physics
 

Get it wrong and see physics in action i suppose ;)

Re: how smart are you -- physics
 

Potential energy, I'd have thought.

If you wire it wrong, the energy has the potential (or potential energy ;) )to throw you across the room (kinetic energy, I believe).

Maybe I've just explained why I could only get a D :D

funny you should say that!.....once tried to insert a plug ito a 4 way. the cover of the plug came off (screw holding it together was missing) and i touched live. sent me dancing round the room and burnt my hand. I always check them now.......lesson learned

Re: how smart are you -- physics
 

It's for those of us who are clueless about physics but do know practical stuff (so we don't feel too dumb)

Re: how smart are you -- physics
 

9/10. Odd set of questions, really.

It's even better than that, if you want to lose weight, climb a mountain. Even without the exercise, gravity is measurably less up there.

Of course, what unscientific people mean by 'weight' is actually mass. Don't get me onto stress and strain...
