Projectile
The “Sepak” itself
Trajectory
The "Sepak" travels in a
curved or parabolic path
3. There are two coordinates usually used to
describe projectile motion: horizontal
and vertical axes.
The horizontal distance traveled by the
projectile is called the range.
While the vertical distance, that is, the
distance from where it was launched to
the top most point of its path, is called its
height.
5. A notable thing to note is that the same
range is obtained from two different
projection angles– complementary
angles.
A body thrown into the air at an angle
of 75º, for example, will have a
similar range as if it were thrown at
the same speed at an angle of 15º.
This means that the 75º angle and 15º
angle are called complementary
angles.
6. complementary angles - angles whose
sum is equal to 90º.
A maximum range is attained when
an object is launched 45º from the
horizontal.
Editor's Notes
When the player hits the "Sepak," you know that it will fall back to the ground due to the effect of gravity; the motion of the "Sepak" is called projectile motion. The "Sepak" itself is called projectile. The "Sepak" travels in a curved or parabolic path called trajectory and will also go towards the ground, especially if air resistance is negligible. This curved path or parabolic path has also been observed in Activity 1 as you tried to launch the marble at different angles on an inclined surface. Regardless of the projection angle, the projectile will always follow a specific path due to the pull of gravity.
