A man pushes a box across a floor. as he increases the force he applies horizontally to the box

a) the kinetic friction decreases
b) the kinetic friction may increase or decrease depending on the velocity of the box
c) the kinetic friction remains the same
d) the kinetic friction increases

Respuesta :

When a man pushes a box across a floor, as he increases the force he applies horizontally to the box, then the kinetic friction remains the same.

To find the answer, we need to know about friction.

What is friction?

  • Whenever a body moves, over the surface of another body, a force comes into play which acts parallel to the surface of contact and opposes the relative motion. This opposing force is called friction.
  • There are two frictions acting on a surface.
  • Static friction:  It come into play between two bodies before when it starts moving. Self-adjusting force and the max value of it is called limiting static friction.
  • Kinetic friction:  It come into play between two bodies when it starts moving. It is not a self-adjusting force.
  • As we increase applied force, kinetic friction will remain same.

Thus, we can conclude that, kinetic friction remains the same when we increase the applied force.

As a guy pushes a box across a floor, the kinetic friction stays constant no matter how much force is applied on the box horizontally.

We must understand friction if we are to find the solution.

Describe friction?

  • A force that works parallel to the surface of contact and opposes the relative motion is always present whenever a body moves over the surface of another body. Friction is the name for this opposing force.
  • On a surface, there are two frictions operating.
  • Static friction: It occurs between two bodies before motion is initiated. Limiting static friction is the term used to describe the maximum amount of self-adjusting force.
  • As soon as two bodies begin to move, kinetic friction is triggered. It is not a force that adjusts itself.
  • The amount of kinetic friction will not change when we apply more force.

We can therefore draw the conclusion that kinetic friction does not change as the applied force is increased.
