Answer 4

the net force applied to an object

Question 5

what is the only way for momentum to not be conserved?

Answer 5

when there is an external net force applied

Question 6

angular momentum

Answer 6

the momentum of a rotating object

Question 7

angular momentum equation

Answer 7

L=IW

Question 8

what is the only way angular momentum won’t be conserved

Answer 8

if there is a net external torque applied

Question 9

inelastic collision

Answer 9

where 2 objects collide with each other and don’t stick together and have some permanent deformations

Question 10

perfectly inelastic collision

Answer 10

where 2 objects collide, stick together and have some permanent deformations

Question 11

elastic collision

Answer 11

when 2 objects collide, bounce off each other but have no permanent deformations
