GCSE physics question
Please could I have part on part b ii of this question. The two arrows will be drag and weight but surely at point b, the arrow for drag will be longer than weight because the object is decelerating? The markscheme says the downward arrow however is longer than the upward arrow? Thanks!

The object isn’t decelerating, it’s just accelerating at a slower rate since it’s about to reach terminal velocity, where it’s then at the constant speed. Since it’s before this termal velocity where the arrows would be equal, weight is larger.
It’d be deceleration if the graph has a negative gradient
I hope that makes sense!

Ohhh, this makes so much more sense! I was so lost but this clears it all up, thank you!!
