No, you're just stupid.
Force = mass * acceleration.
Momentum = mass * velocity.
You seem to be under some stupid impression that force means momentum. An accelerating hand and a constant velocity hand striking someone in the face are both capable of inflicting pain. The negative acceleration of the hand after it hits is a force applied to the hand, and a positive acceleration to the face is also a force.
Tell me about arguing points, when you can't keep up with basic physics or answer simple questions, and then resort to saying "kids will be kids" while talking about hitting me in the face. You're a walking contradiction.
First, you argue like a child. Did you just not call me stupid twice - I didn't insult you - so keep your monkey butt raged comments and shit flinging to a minimum if you have any level of desceny and respect which may be to much for someone like you.
secondly your concept of momentum being different from force if the acceleration is different is clearly wrong and displays a juvinile level of understanding
Question
How is force related to momentum?
Answer
Momentum measures the 'motion content' of an object, and is based on the product of an object's mass and velocity. Momentum doubles, for example, when velocity doubles. Similarly, if two objects are moving with the same velocity, one with twice the mass of the other also has twice the momentum.
Force, on the other hand, is the push or pull that is applied to an object to CHANGE its momentum. Newton's second law of motion defines force as the product of mass times ACCELERATION (vs. velocity). Since acceleration is the change in velocity divided by time, you can connect the two concepts with the following relationship:
force = mass x (velocity / time) = (mass x velocity) / time = momentum / time
Multiplying both sides of this equation by time:
force x time = momentumTo answer your original question, then, the difference between force and momentum is time. Knowing the amount of force and the length of time that force is applied to an object will tell you the resulting change in its momentum
