THE MODEL DIAGRAM

THE EQUATIONS

Displacement(t) = Displacement(t - dt) + (Rate_of_Change_of_Displacement) * dt
INIT Displacement = 1.5 {m}
Rate_of_Change_of_Displacement = Velocity
Velocity(t) = Velocity(t - dt) + (Rate_of_Change_of_Velocity) * dt
INIT Velocity = 0 {m/s}
Rate_of_Change_of_Velocity = Acceleration
Acceleration = Net_Force/Mass
acceleration_due_to_gravity = -9.8 {m/s^2}
air_density = 1.16 {kg/m^3}
Applied_force = weight
cross_sect_area = 0.0133 {m^2}
drag = 0.5*drag_coefficient*air_density*cross_sect_area*Velocity^2
drag_coefficient = 1
Mass = 0.00105 {kg}
Net_Force = Applied_force+Opposing_Force
Opposing_Force = drag
weight = Mass*acceleration_due_to_gravity
