How smart are you -- physics
 

We've had English and Maths, the next installment is physics

7/10 :disturbd: good thing I dropped out of that physics course at Uni ;)

Re: how smart are you -- physics
 

8/10 and I never did Physics

Re: how smart are you -- physics
 

7/10 done it earlier

Re: how smart are you -- physics
 

9/10 I messed up on the smoke detector :erm:

Re: how smart are you -- physics
 

9/10... smoke alarm one caught me out

Re: how smart are you -- physics
 

10/10 but I do have grade A at A-level physics from eons ago (5 years)

Re: how smart are you -- physics
 

Good for you

Re: how smart are you -- physics
 

7/10 never did physics either!

Re: how smart are you -- physics
 

6/10 Perhaps that's why I failed A level Physics all those years ago :dunce:

Re: how smart are you -- physics
 

6/10.. and im uneducated :D almost

Re: how smart are you -- physics
 

9/10 but I could never remember what Newtons was all about!

(And I'm not sure what wiring plugs and the order of planets really has to do with physics!)

Re: how smart are you -- physics
 

8/10

I choose kg for the weight instead of Newtons (who the hell has heard of Newtons for weight ....) & I choose beta radiation for the smoke detector.

Re: how smart are you -- physics
 

6/10 here. And if I recall correctly, newtons are a unit of mass, not weight - there is a difference, though I couldn't tell you what the difference is! :)

Re: how smart are you -- physics
 

I'm not even going to bother - I took Physics at GBSE (all those years ago ;) ) and got a D. When I retook it in the following November, I got a D again, so I've just accepted that that's my natural level :disturbd:

Re: how smart are you -- physics
 

5/10 All the useful to me bits I got right like the plug wiring. Never did physics at school (even then it would be over 30 years ago).

Re: how smart are you -- physics
 

10/10 - sorry ;)

Re: how smart are you -- physics
 

Why apologise? :shrug: You should be pleased.

Re: how smart are you -- physics
 

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

Re: how smart are you -- physics
 

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.

Re: how smart are you -- physics
 

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...

I didnt either and my score shows it!

I only got 1 right!!! (Well I got #1 right also but I cheated,I looked at the answer page first and accidently saw the first one so I got 1 right)

I cant believe I got #3 wrong!!!!!


Im just so upset by whats going on now I guess I cant think right,etc......


It was a fun quiz.......

Re: How smart are you -- physics
 

I've got a degree in Physics and I'm too scared to even attempt this. I remember nothing!

Hehe I bet you would do better than I did!!
