Applications of Force  

After completing their work with the basic dynamics model, students are asked to create a force template model which includes applied and opposing forces. This model serves as the basis for most of the models which follow.

Distance(t) = Distance(t - dt) + (Rate_of_Change_of_Distance) * dt
INIT Distance = 0
Rate_of_Change_of_Distance = Velocity
Velocity(t) = Velocity(t - dt) + (Rate_of_Change_of_Velocity) * dt
INIT Velocity = 0
Rate_of_Change_of_Velocity = Acceleration
Acceleration = Net_Force/Mass
Applied_force = 10
Mass = 2
Net_Force = Applied_force+Opposing_Force
Opposing_Force = -2
