Good evening,

im working on a class that will help to understand radial movement:

i need help in next :

translating phrazes

naming functions.

making the documentation more understandable.

some thing equelant in English to //to do some thing without thinking.

varphi (?) : special latin sign that is the angle (in Radians ) that is changed by time :

Code:

r=R* cos(varphi(t) hat i + R* sin(varphi(t)) hat j

when R is Radius

r is the place vector.

as in normal movement your equation is :

X(t) = x_0 + v_0 * t + (a /2 )t^2

X_0 = is the offset at the start point from the 0 point //could some one please say some thing more understanable.

V_0 = the speed at startup.

a = acceleration.

varphi(t) = varphi_0 + omega_0 * t alpha / 2 * t^2

alpha = omega(t)' = vephai(t)''

omega(t) = omega_0 + alpha * t

alpha = acceleration

Radian = read wikipedia.

Angle to radian = pi * angle / 180

Pi = the ratio between the circumference and radius.

omega_0 = the speed of the angle changing in rad / sec.

omega(t) = the speed at on a specific time

N = the amount of circles it did (point came back to it start point when moving on circular path).

N = varphi (t) / 2 pi

for now the class looks like that :

Code:

class radial_movement
{
private:
float N;
float varphi;
float varphi_0;
float omega;
float omega_0;
float alpha;
int N;
float t;//Time
set(float varphi,float varphi_0,float omega,float omega_0,float alpha,int N);
/*
default values :
varphi_0 = 0;
omega_0 = 0;
*/
public:
radial_movement();
radial_movement(float varphi,float varphi_0,float omega,float omega_0,float alpha,int N);
radial_movement(radial_movement& );
~radial_movement();
set_t(float t);
void calculate();
/*
is called after set
Will calculate (if not set) varphi ,omega , alpha , N
varphi can be calculated if (time != 0) && (scenario) ;
scenario =
(N != 0) , N = varphi(t) / 2 pi.
(omega(t) != 0) ,varphi_0 + omega(t) * t + alpha / 2 * t^2
omega(t) is calculated using :
varphi or alpha or N:
N = 2 pi / omega (t) , N = varphi / 2 pi
*/
float get_varphi();
float get_omega();
float get_alpha();
};
