The potential for static friction is always present due to the nature of the contact surfaces and the normal force. But is a static friction FORCE always present or does it arise in response to...
I have a pretty simple question: What is the purpose of a resultant velocity in 2D motion? Is it used for anything besides finding the vertical and horizontal components?
For example, I was given this problem:
