17
Q

how do you change an objects motion

A

apply a force

18
Q

what is the impulse equation

A

f*T=P

19
Q

what are two ways in witch an object does change

A

either mass and velocity can change

20
Q

assuming the mass of an object does not change what would case its momentum to change

A

velocity change in motion.

21
Q

impulse

A

applying force to case a change in motion

22
Q

change in momentum

A

change in motion

23
Q

impsct time

A

(T) amount of time a force is applied for

24
Q

elastic collision

A

bounce collision

25
Q

inlastic

A

stick collison

26
Q

consvation

A

no change

27
Q

law of consvation

A

the total momentum of each object before the collision is equal to the total momentum of each object after the collision.

28
Q

netweens third law

A

for every action there is a equal but opposite reaction

29
Q

collision

A

when things collide

30
Q

exsplotion

A

smash/break apart
huge burst of energy

31
Q

scalar

A

described by its magnitude

32
Q

netweens 1 law

A

anything in motion stays in motion and a object at rest tense to stay at rest

33
Q

netweens 2 law

A

F=m*A
