angular momentum

Question 1

what is angular momentum

Answer 1

an objects motion around an axis

Question 2

what two things does angular momentum depend on

Answer 2

1. MOMENT OF INERTIA
2. ANGULAR VELOCITY

Question 3

what is moment of inertia

Answer 3

an objects resistance to change its state of motion WHEN ROTATING

Question 4

what is angular velocity

Answer 4

the rate of movement in rotation

Question 5

how do you calculate angular momentum

Answer 5

AM=moment of inertia x angular velocity

Question 6

what is the relationship between moment of inertia and angular velocity

Answer 6

INVERSELY PROPORTIONAL

Question 7

what two factors does moment of inertia depend on

Answer 7

1. mass of the object
2. the distribution of mass around the axis
   -the closer the mass is to the axis of rotation, the easier it is to turn, and therefore moment of inertia is low and angular velocity is high
   -the further the mass is to the axis of rotation, the harder it is to turn, therefore moment of inertia is high and angular velocity is low

Question 8

is angular momentum constant

Answer 8

yes, unless an external force such as friction or air resistance acts upon it
