Module 6 Unit 2

Question 1

What is angular velocity

Answer 1

Angular velocity is the expression of the rate of change of an angle per time unit

Question 2

What is angular velocity

Answer 2

Angular velocity is the expression of the rate of change of an angle per time unit

Question 3

How is rpm converted to rps

Answer 3

When converting from rpm to rps one devideds by 60 when going the other way one muiltiplies by 60

Question 4

How is angular velocity converted to peripheral velocity

Answer 4

It is muiltiplied by the radius (v=wR)

Question 5

What is the symbol of angular velocity when calculated in radians

Answer 5

When angular velocity is expressed in radians the symbol is rad.s^-1

Question 6

What is peripheral velocity

Answer 6

Peripheral velocity is the linear velocity at any point on the circumference of a circle

Question 7

How is angular velocity calculated

Answer 7

1. Angle formed÷time
   2.w=2πn

Question 8

How is peripheral velocity calculated

Answer 8

V = nπD
V = wR
Where
n = number of rotations per second
w = angular velocity
