1. The problem statement, all variables and given/known data Thanks for looking. My understanding of Newton's Second Law, F=MA, is: If I give some mass a force, it will accelerate at some rate. Imagine an infinite, frictionless surface. If I give a box of 1kg a push of 6 Newtons, it will accelerate at 6 m/sec2. So, at t=0, v=0. at t=1, v=6. I have two questions: 1) What is v, at t=0.5? is it 3? is it 6? 2) what is v, at t=2? does it remain 6, or continue accelerating to 12? and why? What I'm trying to ask is, is the A in F=MA is an ongoing acceleration, that keeps accelerating the box as long as there is no friction, or is it a single acceleration, giving an addition of 6 m/sec2 once, and that's it? 2. Relevant equations F=MA 3. The attempt at a solution Asked my sister and someone who graduated in physics, read the wikipedia article, searched Google, read relevant chapters in Conceptual Physics, and watched Prof. Walter Lewin (Best Accent!). No one addresses my questions. Thank you very much!
