Physics practical grams or kg?

[Knight]

its ok i think

yo-ho

does this make my point clear? if not prove me to be wrong.

yes the gradient is negative

Yeah true

someone plz confirm. for eg: on the graph cause i got such small values so i put the valuse as xx to the power of -4 for it to look neat.
so all my values are meter/grams so will i be penalized for this, cause some ppl said it has to be meter/kilograms THX

no I did the same as you, put them x10^-4 .. its okay, and I didn't change it to grams.. you don't have to. In fact why would people do that? there was no need and no marks for it

 

[angelicsuccubus]

mine was negative too and i consulted with many of my classmates....most had a negative gradient

mine was negative too but every other kid in the school had a postive gradient =[

 

[angelicsuccubus]

I even have my values and the table and I keep redrawing it.. it doesn't make sense how people got a positive gradient.. anyway what was p and q?

Anyone who wants to discuss the paper inbox me.

I also got negative!

 

[Rashmit Arora]

Mine was negative too!

was a positive gradient! there was a linear relationship between h0-h/m and 1/m

we had to plot 1/m on x axis and h-h/m on y thats why you should get positive gradient

 

[JD REBORN]

Yeah gradient should be positive cuz both quantities on x and y axis increased.As far as negative is concerned let me tell u this:the 1 mark for gradient is the hypotenuse of the triangle must be at at least half the length of the drawn line.Both read-offs must be accurate to half a small square.The method of calculation must be correct.It has nothing to do with the value u obtained.However i dont think the gradient was negative.But if it wasnt negative and u obtained negative then u might lose the mark in the next part in calculating value of P.So hw did everybody calculate P?

mine graph was not correct values for my graphs at some points were same ,that y mine graph was not in straight line so hw many marks we lose can anybody tell me..

 

[Abhishek Solanki]

mine gradient was positive..

hey i also did the same thing..

 

[Sarmad Furqan]

I used grams and centimeters today.

you should have used metres...isn't it as the first reading recorded was in metres for question 1....btw chill..

 

[Abhishek Solanki]

can u tell me hw much we lose for if we had not plot the graphs..i hurry i forgot to see marks ..

 

[Abhishek Solanki]

yes i had used meters..and kg as per SI system

 

[Sarmad Furqan]

yes i had used meters..and kg as per SI system

good...but i've used grams instead of metres..

2 marks..
