In splitting logs with a hammer and wedge, is a heavy hammer more effective than a lighter hammer? Why?this question is about physics

The effectiveness of a wedge in splitting a log depends on
a number of factors. These include the shape pf the wedge - particularly the angle of
the wedge, the size and strength of the log to be split, and the force that is applied
to the wedge to drive it in. The force applied o the wedge in turn will depend on things
like the weight of the hammer used for driving the wedge, and the speed with which it
strikes the wedge. Other things being equal, a each stroke of heavier hammer will drive
the wedge deeper as compared to a lighter hammer. The sped with which the hammer strikes
the wedge has no relationship with the weight of hammer. Generally higher the height
from which the hammer is brought down to the wedge, greater is the speed at which the
hammers strikes the wedge.
