1. We identified the sliders that
changes the angle, gravitational acceleration and power of the gun.
2. We draw a circle that has same
length of radius with the power of the gun, so we when we change the power of
the gun circle will be greater.
3. We draw a vector on the circle with
the angle which we identified with slider, so when we change the angle vector
still be on the circle and angle will change too.
4. We find the perpendicular lines from
the point B which is the end point of vector to the x-axis and y-axis. Thus, we
found the Vy, and Vx which are the horizontal and vertical speed of the particle
that we throw with the gun.
5. We identified the time as t with a
slider and the end point of the slider fixed with the formula of tfly=2.V.sin(α)/g or 2.Vy/g
6. Height also identified the physic
formula of H(x)=V.sin(α).t-1/2gt2
and graph of it drawn.
7. Range of the particle has calculated the formula
M(x)=Vx.t
8. Then the Throw button and reset button identified.
9. The rest of the game is actually decoration. You can
change it however you want.
