Answer to Question #308098 in Mechanics | Relativity for chrissy

Question

A cardboard box is sliding across the floor after some initial push gets it moving. The box is not being pushed anymore, just sliding across the floor. The floor is exerting friction on the box. What will happen to the box and why?

Answer 1

Answer

  

2. Play with this simulation of Motion and Forces, working through all four sections. In each case, turn ON the display of the force vectors using the checkboxes.

The Role of the Normal Force   In both cases, static and kinetic, the harder the two surfaces are pressed into each other (in other words, the normal force, F_N), the greater the frictional force.

  

 Need more force pushing the box rather than pulling.
