Answer:-
Force depends on mass and acceleration of a particle. Though axe has a very less acceleration, but the mass is very high. Thus, force increases. Also, it has sharp edges which increases thrust. So, it strucks on it. It produces a very high force.

the cutting of the wood by the axe depends on the Pascal's law and the law of conservation of mechanical energy.
Explanation:
- When the axe is lifted up there is a gain in the potential energy. And then there is is the X which is stuck on the the stem of the plant which is at a lower potential energy. Hence there is increase in kinetic energy. also there is some additional energy which is provided by the muscle of the person.
- This is suddenly brought to rest Hence a braking force is applied on the the wood. Since the end of the the axe is very sharp due to Pascal's law since the area is less the force is very high.
