Circular motion

What is period (T)

Time in seconds to complete one revolution

What is frequency (f)

Rate of rotation, # of revolutions per second

High frequency = WHAT

High frequency = FAST

Low frequency = WHAT

Low frequency = SLOW

What is the speed equation

V = 2πr / T

What is angular position (θ)

Angle measured counter-clockwise from the x-axis

measured in radians

What is arc length (S)

Actual distance travelled by the particle form the x-axis

What is the equation between angular position and arc length

S = rθ

A particle with larger angular velocity undergoes larger WHAT in each WHAT

A particle with larger angular velocity undergoes larger ANGULAR DISPLACEMENT in each SECOND

What is the equation for angular velocity 

w= Δθ / Δt

What is the equation for instantaneous velocity

w= dθ / dt

What are the units for w

rad/s

What is omega (w)

Hoe many radians you travel through per second

If it has uniform circular motion than it has WHAT

If it has uniform circular motion than it has CONSTANT w (constant speed)

Relation between angular and tangental velocity:

• θ = Angular position equation = WHAT

• w = Angular speed equation = WHAT

Relation between angular and tangental velocity:

• θ = Angular position equation = Sb(linear) = rθ (angular)

• w = Angular speed equation = V (linear) = rw (angular)
