Chapter 16: Circular Motion Flashcards
1
Q
How do you convert angles from degrees to radians
A
divide by 180/π
2
Q
what is angular velocity
A
velocity of an object in circular motion in terms of radians
3
Q
what are the three angular velocity equation
A
w = 2πf [f ifs frequency] w = (2π)/T [T is time period] w = θ/t
4
Q
what is the centripetal force
A
Force that keeps an object at uniform speed whilst it moves in circular motion
5
Q
what are the two velocity equations for circular motion
A
v = (2πr)/T v = r x w
6
Q
what is centripetal acceleration
A
acceleration of an object travelling in a circular path at constant speed
7
Q
what are the two centripetal acceleration equations
A
a = v^2/r a = r x w^2
8
Q
what are the two centripetal force equations
A
F = (m x v^2)/r F = m x r x w^2
