Question

I have a question regarding using primitive shapes and simulating a circle to be free falling. How would I go about this? Do I use the formula for gravity?

Answer 1

Gravity is just constant acceleration downwards.

Pseudocode:

const Vector3D Gravity=(0, 0, -9.8 m/s^2);
Vector3D Acceleration=Gravity;//insert other forces here
Vector3D Position+=Speed*DeltaT+0.5*Acceleration*DeltaT*DeltaT.
Vector3D Speed+=Acceleration*DeltaT;
