Question

A particle is traveling in a vertical circle at constant speed. One can conclude that ______ is constant
A)velocity
B)acceleration
C) net force
D) Apparent weight
E) none of the above

Answer 1

Why wouldn't acceleration be constant?

Answer 2

Because its direction is changing constantly!

Answer 3

So what would be the correct answer?

Answer 4

I guess E

Answer 5

or C

Answer 6

Yes, it should be C!

Answer 7

The answer in the book is E

Answer 8

wouldnt the answer be D because the weght wouldnt change right?

Answer 9

haha oh those problems that we always end up over thinking lolz

Answer 10

It is moving in a vertical circle! So, apparent weight will change continuously!

However, the 'magnitude' of acceleration is constant.. So, net force must be constant!

Answer 11

he just said E was the answer.. lol

Answer 12

But then i said C, after a bit of mind-work!

Answer 13

lol

Answer 14

I'm still confused

Answer 15

I gave you a proper explanation why it should be C (net force)!! There's no room for confusion!

Answer 16

Ok! I'll see what my teacher says and i'll get back to you on that!

Answer 17

net force is constantly changing direction though... so it should be E

Answer 18

yeah, the the options are bit tricky.. The magnitude of:
A)velocity
B)acceleration
C) net force
remains constant but they are all vectors and their direction don't remain constant! So, to be precise, they are not constants!

Thus, the answer is 'none of the above'
