Problems on Friction
... Problem 1: A dockworker loading crates on a ship finds that a 20-kg crate, initially at rest on a horizontal surface, requires a 75-N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 60 N is required to keep it moving with a constant speed. Find the ...

... If body A exerts a force F AB (action) on body B, then body B exerts a force FBA (reaction) on A of the same intensity but in the opposite direction. In other words, for every action there is an equal and opposite reaction: FAB = - F BA The forces of action and reaction act on different bodies. Newt ...

... Hypothesis: rate of acceleration is directly related to the net force. On the other hand, the rate of acceleration is indirectly related to the mass of an object. Analysis: talk abut experimental error and reasons for it(friction). We ignored pullies too. The meanings of the equating of the line. ...
