No, it's not. Where the heck did you get that idea?

Let's get that straight right now! Sports reporters writing about football players may use the words force, momentum, inertia, and kinetic energy interchangeably, but in physics they are not at all interchangeable. Perhaps it would be good to go back to your 7th grade science book and find out what momentum means. > If a football player runs faster, he will impact the > opposing team player harder.

Forces can *prevent* something from moving, and forces can make an object that is moving LOSE its motion. Please, John, at least start with proper definitions of words before you start mouthing off nonsense. >, or that which can cause a mass > to move. "Momentum is a specific force which can be attributed to > having some mass be in motion with a specific velocity." No sir! Momentum is not ANY kind of force.

Look in your 7th grade science book, or the same one where you saw that work is force times distance. Look there for what the expression for momentum is.

Don't be silly! When an object is dropped from a height without resistance, there certainly is a force applied to the object -- gravity! When a hockey player hits a hockey puck on ice to accelerate it, there is no resistance, and yet he has to apply a force to accelerate it! This is Newton's 2nd law! You may have heard of it: In order to accelerate an object with mass, you have to apply a force, with the amount of force being the mass times the acceleration.

For example, when a golf ball Is struck, it's hard to quantify what happened except that we can measure its velocity v as it leaves the club. Multiply by mass in slugs to get momentum = mv (where m = weight/32.2f/ss) (slug equals pound/32) The applied force can be found out by solving the equation, knowing the momentum: Force times time equals mass times velocity f*t pound seconds = m*v slugft/sec (known) if the force function is a rectangle. (for any shape, use Dirac's impulse integral) Suppose we calculated the right-hand side mv = 100 slug feet per second, and if we estimate that the force rectangle lasts .01 seconds, the corresponding force at impact would be 10,000 pounds (100/.01). Momentum can be expressed as force times time or mass times velocity. In any consistent set of units such as Newtonxseconds or kg x meters per second. John Polasek
