Chapter 16: Circular Motion

Question 1

How do you convert angles from degrees to radians

Answer 1

divide by 180/π

Question 2

what is angular velocity

Answer 2

velocity of an object in circular motion in terms of radians

Question 3

what are the three angular velocity equation

Answer 3

w = 2πf [f ifs frequency]
w = (2π)/T [T is time period]
w = θ/t

Question 4

what is the centripetal force

Answer 4

Force that keeps an object at uniform speed whilst it moves in circular motion

Question 5

what are the two velocity equations for circular motion

Answer 5

v = (2πr)/T
v = r x w

Question 6

what is centripetal acceleration

Answer 6

acceleration of an object travelling in a circular path at constant speed

Question 7

what are the two centripetal acceleration equations

Answer 7

a = v^2/r
a = r x w^2

Question 8

what are the two centripetal force equations

Answer 8

F = (m x v^2)/r
F = m x r x w^2
