- Hey! Can you explain me what's going on? I don't understand that drawing.
- Sure. The large arrow pointing to the right is the applied force. This means is the force that has being exerted into an object. The small arrow to the left is called friction force, it the force that opposes the applied force.
- Oh I get it, so the arrow in the top must be the Natural force. And the arrow pointing down is the gravitational force that keeps the ball on the ground. And the applied force comes from the work you applied into the ball. And to calculate the power you just have to divide the amount of work/time. But, how does momentum work?
- Yes, what you said is correct. Going back to your question, the more velocity the ball has, the more momentum it has too. in order to calculate it you must know the weight of the object and its velocity. You start by using the formula F=ma.
- Great!, now I understand. Thanks!
- Understanding the physics behind an object is pretty easy right? You are welcome!
