I would like to go over my answers along with ask for help on a few.
"For each of the following interactions, identify forces that comprise a 3rd-Law Pair (or Action-Reaction Pair)."
(a) A hammer hits a nail.
Action: hammer
Reaction: nail
(b) You punch your friend in the face.
Action: punch
Reaction: friends face
(c) Earth's gravity pulls down on a physics book.
Action: gravity
Reaction: physics book
(d) A helicopter blade pushes air downward.
Action: helicopter blade
Reaction: air
(e) A round gets shot out of an AK-47.
Action: AK-47
Reaction: round
(f) A guy throws a ball on ice.
Action:
Reaction:
(g) Mario hits his head against a coin block.
Action:
Reaction:
(h) Michael Jordan lifts off with his Air Jordan’s
on the Chicago Bulls’ basketball court.
Action:
Reaction:
(i) WALL-E uses his fire extinguisher to propel himself toward the spaceship Axiom.
Action:
Reaction:
According to Newton third law, to every action there is an equal and opposite reaction force.
A) hammer hits nail.
Action = force applied by hammer on nail.
Reaction= force by nail back to hammer.
B) You punch your friend on face.
Action= punch on the face
Reaction= force from face back to the punch.
C) Earth gravity pull down on a a physics book.
Action= force of gravity pulling the book
Reaction= gravity force due to book pulling the earth
D) A helicopter blade pushing air downward
Action= force by blade on the air in downward direction
Reaction= force by air on helicopter blade in upward direction.
E) A round gets shot out of an Ak-47
Action= force from AK 57 on the round during shot.
Reaction= recoil force due to round in opposite direction of its motion.
F) A guy throws a ball on ice.
Action = The ball hits the ice.
Reaction= the ice hits the ball back due to which ball bounces..
G) Mario hits his head against a coin block.
Action = Mario's head hitting the coin block,
Reaction= coin block hitting back the head of Mario.
H) Michael Jordan lifts off with his Air Jordans on the Chicago bulls basketball court.
Action = Michael Jordan applied force on the floor in downward direction.
Reaction= the floor applies force on Michael Jordan in Upward direction.
I) Wall- E uses his fire extinguisher to propel himself towards spaceship Axiom.
Action= The fire extinguisher releases air at high pressure in the atmosphere. So force is developed from extinguisher to to atmosphere.
Reaction= The atmosphere applies equal and opposite force to the fire extinguisher and thus propels Wall-E in opposite direction.
