History of Archery(Middle Stone Age-Now)
Figure -1
One of the oldest arts, archery is the skill of using a bow to shoot
arrows through the air along a parabolic trajectory. Archery is
originated in Africa around the later Middle Stone
Age(approx.70,000 years ago). Ancient Egyptians are the first and
foremost people who were known to utilize bows and arrows. The
intention of this usage is for hunting and warfare back then and
they adopted archery around 3,000 BC. Later on, China also
started to adopt archery around the Shang Dynasty (1766-1027
BC). Nowadays, it is mainly a competitive sport and recreational
activity.

Equipment for Archery
Bows
In archery, four main types of bow named the recurve
bow, the compound bow, the longbow and the barebow
are mostly used. A comfortable grip, a smooth draw
cycle, a comfortable valley, and minimal hand shock are
the must things to check when looking for a good bow.
Historically, these bows were made from wood.

Modern shafts are made from aluminium, carbon
fibre reinforced plastic, or a combination of materials
while traditional arrow shafts are made from strong,
lightweight wood, bamboo, or reeds.

Arrowheads
An arrowhead is a tip, usually sharpened, that was used as a tool in
hunting and as a weapon during warfare. Native American arrowheads
were used during ancient times, specially in the Stone Age.

Interconnection between Archery and Projectile Motion
(Drawn by Shon Lai Yee Mon)
A projectile is any object thrown or launched into space upon which the only acting force is gravity.
This doesn’t mean that no other forces are acting on it, just that impact from them is not obvious
compared to gravity which is the primary force. The parabolic curved path followed by a projectile
is called as a trajectory. Projectile Motion is the motion of a thrown object which is also named
projectile such that the horizontal component of the velocity is constant, and the vertical motion
has uniform acceleration due to gravity. The horizontal and vertical motions are completely
independent of each other which means that motion in one direction has no effect on motion in
another direction. However, the time taken for a projectile motion in horizontal direction and
vertical direction are the same.

When the archer releases the bowstring, the pulling force by an archer which is also the initial contact
with the arrow propels the arrow upward at an angle. Velocity at y axis is positive. In this case, we can
assume this arrow as a projectile which is moving through the air in the curve of a parabola way. The
arrow rises to a certain point which is the maximum height from ground level where the velocity is equal
to zero. Then, the arrow’s pathway eventually curves downward under the influence of Earth’s gravity
and velocity at y axis is negative as it accelerates downward. Here, you don’t have to consider about air
resistance or Earth’s rotation. This type of motion is called projectile motion. As explained by the
theories of projectile motion, the arrow has a constant horizontal velocity and a constant vertical
acceleration.
The role and impact of projectile motion in real life
The application of projectile motion in physics and
engineering are numerous. Meteors as they enter Earth’s
atmosphere, fireworks, and the motion of any balls in sports
are apparent examples for us. In this archery case, bows and
arrows provide many people’s lives with better quality by
being a weapon for hunting animals for food, as a defensive
or conquering weapon in battles in ancient times, or as an
instrument in competition in modern times. Moreover, we
can improve our skills of precision, control, focus, patience,
determination and physical strength by playing archery
sport. On the other hand, this archery was also one of the
weapons that can kill countless of innocents during wars
back then and hunting also leads to extinction of nature’s
species.
