Friction ppt - Cobb Learning
... Why do sports shoes have more tread on them compared to dress shoes? Because more tread leads to more bumps, which leads to more friction. Athletic shoes need more friction to allow for greater acceleration (rapid sprints, sudden stops, and quick turns), whereas dress shoes do not require the same ...

Newton`s Second Law of Motion
... you push on a cart, the faster it goes. Is the cart’s velocity related to the force you apply? Or, is the force related to something else? Also, what does the mass of the cart have to do with how the motion changes? We know that it takes a much harder push to get a heavy cart moving than a lighter o ...

By the same v v2 v1 argument as in the question above, one can show that the acceleration is straight down when the mass on the extreme right with the string horizontal. Since the acceleration is straight down, the net force must be straight down, so there can be no ...
