impulse

Question 11

center of mass

Answer 11

average of masses factored by their distances from a reference point

Question 12

center of mass allows us to?

Answer 12

describe the movement of a system by particles of a single point

Question 13

equation for
impulse = change in momentum

Answer 13

F x /\ t = m x /\ v
N x s = kg x m/s

Question 14

conservation of momentum

Answer 14

momentum is conserved in all collisions in isolated systems; no external forces

Question 15

conservation of momentum equation

Answer 15

m1v1i +m2v2i = m1v1f + m2v2f

Question 16

conservation of momentum equation meaning?

Answer 16

momentum before = momentum after

Question 17

elastic collisions

Answer 17

kinetic energy is not conserved
- objects bounce off of each other

Question 18

perfectly inelastic collisions

Answer 18

kinetic energy is conserved
-objects stick together and move off as one

Question 19

inelastic collisions move which way after impact?

Answer 19

Which ever way had more velocity

Question 20

inelastic collision equation?

Answer 20

m1v1 + m2v2 = (m1 +m2) Vcom
