Hello, I have a question regarding how I'm simulating motion using the common time integrating approach to simulating rigid bodies.
I have net forces and solve for position from those:
acceleration = force / mass
velocity = initial velocity + acceleration * time
position = initial position + velocity * time
but if you combine the above and distribute you get something that matches the kinematic equation, but is missing the one half term. Where'd it go?
position = initial position + (initial velocity + (force / mass) * time) * time)
position = initial position + initial velocity * time + (force / mass) * time^2
which does not equal the kinematic equation
y = y0 + v0*t + (1/2)a*t^2
Where'd the one half go?
