physics chapter 7: newtons third law of motion (the law of action and reaction)

action and reaction are both …

forces

action and reaction are not …..

motions

action

object 1 pushes or pulls on object 2

reaction

object 2 pushes or pulls on object 1

why dont you feel a push back

you have more weight than what youre pushing on normally

action: you push the chair to the right what’s the reaction?

the chair pushes you to the left

all forces come in……(interaction

pairs

how to find the reaction of an action force

flip-flop the subject and direct object and reverse the direction

action: the hammer pushes the nail downward

the nail pushes the hammer upwards

action:you push the water backward

the water pushes you forward

all forces are…. by and on something

exerted

what is exerted

caused/act on

action and reaction forces…..

Never act on the same object

just because two forces are equal and opposite does not make them an

action and reaction pair
