No kinetic energy?
I put gravitational potential energyTGP666\" post_id=\"1938962\" time=\"1569908169\" user_id=\"181285:
What did u guys put for the toy car sliding down plastic track with a twirl question
The main form(s) of energy the toy car has at point C(Highest point of the twirl)? -

What is the qn and the options for this kinetic energy qn?
I put kinetic to potential as during the moment when the ball is bouncing on the floor, it bounces back up so should be _____ to gpe. Since sound energy is lost and not being converted into gpe(or else the ball will keep bouncing), hence, answer should be ke to gpe.
Also, what are the answers for seed leaf mass qns -

Q sthg like that - what does the graph show?
Can he recall the question?sweetbaby\" post_id=\"1938935\" time=\"1569904076\" user_id=\"16633:
[quote=thebusybee post_id=1938923 time=1569903067 user_id=4562]DS said he spotted a few tricky mcq qns which needed to read a few times to understand.
There's a qn abt young plant, after reading the graph carefully, his ans is - the seed starts to grow. Hope he got the right ans!
Choices not in order-
1) root starts to grow at x
2) root comes out before shoot
3) seed starts to grow at x
4) **he forgot but definitely wrong**
*note - straight line is Seed Leaf, dotted line is Seed
