Hey guys, how was your edexcel physics unit 1 (old syllabus) (WPH01) exam?

This was the last sitting for this syllabus so i hope we all pass with our desired grade! Any predictions for the grade boundary?

Edit: I forgot to mention in the title that this is an IAL exam

I can’t remember exactly but my calculated answer was
sth x 10^-4 m which i converted to mm since the question asked for it.

Also what was the value for force? The rope was 70 degree to the vertical. Did i have to calculate the Tension or did i have to use the weight only? I might lose 1/2 marks in this question.

if i wrote that 1 mm is 1 X 10-3 and my answer is less so its safe would that be okay if i didnt convert it ?

weight is equal to the tension in the rope since the painting doesnt move. each side was 10.8 cos 70

Oh i remembered now, my value for the extension was around 0.76mm so i wrote its safe since 0.76mm>1mm

And i think you did have to convert your answer. Or convert 1mm to m.
Can you recall if the original length was in metre or mm?
Cross sectional area was in meter.

**** i calculated the value for tension
but i used only 10.8 for the value of force so i will lose mark and my answer is not correct then.

i so hope the grade boundary for an A is in the late 40’s (47-48). what do u guys think

OR, you could convert 1mm to m and compare your answer to it.

what about the energy question when you had to explain why the gpe is much less than the total energy thing question

Ugh i had only 2 mins left when i was answering that.
I couldn’t even read the question properly. I just wrote the principle of conservation and wrote that some of the enery have converted to heat energy.

i don’t think so.
How did you answer the projectile question?
how did you calculate the horizontal component?

Waaaaaaaaaaaaaaiiiiiiiiiiiiiiiii tttttttttttttttttt, was the value for extension = 1.8 mm ?
Cz I think I didn't take the components, is it wrong ?

Yeah wrong ☹️
i didnt take the component either, i used F=10.8N
but my final answer was still somehow less than 1mm. So i wrote its safe.
