recoil

the backward jerk of a gun when it is fired

a movement back from an impact

draw back, as with fear or pain; "she flinched when they showed the slaughtering of the calf"

come back to the originator of an action with an undesired effect; "Your comments may backfire and cause you a lot of trouble"

spring back; spring away from an impact; "The rubber ball bounced"; "These particles do not resile but they unite after they collide"

spring back, as from a forceful thrust; "The gun kicked back into my shoulder"
