Ficticious Flashcards
1
Q
What must happen for circular motion?
A
A constant force must act on the body towards the centre of the circular path
2
Q
What is the centripetal force?
A
It is the only force acting in circular motion
3
Q
Equation for centripetal force?
A
F=mv^2/r
4
Q
What is the centrifugal force?
A
It is generated by acceleration and therefore considered a ficticious force (we can still calculate with it)
5
Q
In the ficticious forces equation, what is F?
A
F is the centripetal force - usually calculated using F =mv^2/2
6
Q
In the ficticious forces equation, what is 2mwxv’?
A
It is the coriolis force - it depends on speed - useful to find things like apparent weight
7
Q
In the ficticious forces equation, what is mwx(wxr)?
A
It is the centrifugal force - it depends on position - useful to find a period
