Tac-Tics - thank you very much for the additional explanation. I've taken three semesters of calculus up to multivariate calculus and two semesters of physics. I rememeber learning that velocity is the first derivative of position and that acceleration is the second derivative of position and...

Okay! Thanks again very much!

Last question: When is it possible for something with mass and velocity to have zero acceleration? It seems there has to always be some infinitessimal change in velocity, therefore having velocity means having acceleration?

Thank you Tac-Tics!

Thank you Doc Al! How about a bullet that is moving through the air at a constant velocity. Is that a force? If so, how does it fit into F= ma?

Hello, So I know F = ma. If a particle is moving at constant velocity and strikes something, doesn't that mean there will be zero force, beacuse there is no acceleration? I'm having a hard time conceptualizing this, as it seems there would be a large force. For example, if a bullet could...
