Edexcel IAL Physics Unit 1 WPH01 May June 2016 Discussion

To be honest, the questions were not too tough, what made it hard was the severe shortage of time

If i am not wrong c12 is just tommorow..😂
Pay special attention to the area under the curve from jan 16..

From where does this multiplying the time by 2 comes from?..we were dealing with just the fall of the ball i.e (from x to y)..its not like the ball moving up and coming down so there is no point of doing anything with the flight time..just imagine it as if the ball has fallen from a roof and we are told to workout now..

btw your username is freakin hilarious xD
i mean you must be indian or pakistani because these guys eat roti kebab xD
Im pakistani too and i found it ridiculous xD

coz I didn't take rANGE BETWEEN X AND Y I TOOK WHOLE AND TIME WAS ALSO TWICE FOR THAT REASON BUT BOTH METHOD GIVES SAME ANSWER AS RATIO IS SAME

Yeah you might be right..cant tell until we get the model ans so yeah wait for 2-3 days may b

Since most of the people found it slightly challenging there is a small possibility of them setting a lower grade boundary.

About 1/3 population of the world there are bdeshis too..😂

ahan btw it will be posted by physics and maths tutor right on their fb page!

Ok so today's paper then!
Here are my answers, feel free to check me and add any I miss!

•The rose petals olympics question;

Copper: because it is ductile and therefore can be beaten into shapes plus it is resistive to high Temps
Steel: because it is tough and therefore won't break under the stress of the weight.

•The spider question:

I used the weight of the spider plus the weight of the fly times gravity to find the acceleration.

•Car Spring Question:

I argued that a stiffer spring would be dangerous on a bumpy road causing it to bump and tumble which could lead to injury.

•Hammock Question:

I resolved the vectors and received a value of around 617N. Some people got 643 so I'm not sure!

•Tennis ball Question:

I measured the length of the image with my ruler and argued that since the ball falls the vertical distance in 1/20th of a second and because we know gravity to be 9.81 adding to that my measurement , we could calculate the distance the ball fell between X And Y.


•Rower Question:

I drew rectangles underneath the graph and then added them all up to give me an approximate value for the amount of work done.

•Viscosity Question:

I talked about plotting a graph of radius against flow rate and then using the gradient to confirm a value for the viscosity!

Well these Are the parts I remember! What about you?

For the horizontal velocity of the ball ques i wrote 1.8÷7....and got answer about 0.26 m/s maybe......will it fall in the range of the answer???

well... the exam was sorta medium difficulty :V
That spider and fly question was damn tricky though xD
what was your value for acceleration in that question ?

Mine was 7.2 meters per second squared. What was yours?

Ial unit 1 physics may 2016 is here...not sure though if all the model ans. are correct..
