Application of Rigid Body Kinetics

Question 1

What is the angular momentum of as spinning body in x-y?

Answer 1

I_zz d/dt \omega

Question 2

What is the KE of a rolling body in x-y

Answer 2

mv^2/2 + I_zz,G \omega^2/2

Question 3

What is centric impact?

Answer 3

The contact normal, velocities, and center of gravity are all colinear

Question 4

What is skew centric impact?

Answer 4

Centric except velocity condition not met

Question 5

What is an assumption for collisions?

Answer 5

All forces except impact forces can be neglected

Question 6

What is radius of gyration k?

Answer 6

k = \sqrt{I/m}
