1. Hi guys just wondering when there is a question asking you to sketch a speed time graph or a velocity time graph, does the shape have to be very precise though? For example if you are told that the acceleration is 3ms-2 do you have to draw a very steep line or does it not matter as long as you have the right shape? Sometimes in the mark scheme I see that the lines are quite steep but sometimes it doesn't. Would you lose a mark if you draw two lines roughly the same though they have different accelerations? This is for edexcel m1 exam. Cheers
2. Hey,

Typically the questions are 2-3 marks, so they dont expect you to be precise just have the general points and mark on the given times / velocities.

However if they give you the acceleration and deceleration for example, you may get a mark for drawing one steeper than the other if that makes sense.

What about q6 in this paper? https://3b0a7b1bc87f5381e60f8f717510...%20Edexcel.pdf

I never saw any penalty for steep lines in the mark scheme though.Thanks.
