Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
According to Newton’s third law of motion, when a hammer strikes and exerts force on a nail, the nail??
A
creates a friction with the hammer
B
disappears into the wood
C
exerts an equal and opposite force on the hammer
D
moves at a constant speed
Explanation: 

Detailed explanation-1: -Newton’s third law states that for every force, there is an equal and opposite force. The force of the hammer on the nail will be equal in magnitude, but opposite in direction, to the force of the nail on the hammer. Mathematically, that would mean . The nail would exert force on the hammer.

Detailed explanation-2: -A hammer hits a nail, driving the nail downwards into a piece of wood. The “reaction” is the force of the nail pushing upwards on the hammer, which stops the hammer.

Detailed explanation-3: -Newton’s Third Law: Action & Reaction His third law states that for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A. In other words, forces result from interactions.

Detailed explanation-4: -Newton’s Third Law says that every interaction involves two forces-in this case (1) hammer pushes nail, and (2) nail pushes hammer. When a hammer hits a nail, Newton’s Third Law says that the force that the hammer exerts on the nail is exactly the same size as the force the nail exerts on the hammer.

Detailed explanation-5: -According to Newton’s third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.
