Question 7

when the speed of an object doubles its momentum…

Answer 7

doubles

Question 8

newtons third law

Answer 8

whenever one object exerts force on a second object, the second object exerts an equal and opposite force on the first object

Question 9

momentum before and after

Answer 9

momentum before firing is 0…after firing the net momentum is still 0

Question 10

the law of conservation of matter

Answer 10

in the absence of an external force, the momentum of a system remains unchanged

Question 11

elastic collisions

Answer 11

• when objects collide without being permanently deformed

- the sum of the momentum is the same before and after each collision

Question 12

inelastic collisions

Answer 12

• colliding objects become distorted during the collision

- momentum conservation remains true

Question 13

totally elastic collision

Answer 13

whenever colliding objects become tangled or couple together
