Figure out horizontal force necessary to move an object

Click For Summary
SUMMARY

The discussion centers on calculating the horizontal force required to move an object when the coefficient of kinetic friction is zero. It is established that if kinetic friction is zero, static friction is also zero, meaning no force is needed to maintain motion once the object is in motion. An initial impulse is required to overcome static friction, but thereafter, no additional force is necessary to keep the object moving.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Knowledge of friction coefficients, specifically static and kinetic friction
  • Basic principles of impulse and momentum
  • Familiarity with the concept of force in physics
NEXT STEPS
  • Study Newton's laws of motion in detail
  • Learn about the implications of frictionless surfaces in physics
  • Explore the concept of impulse and its effects on motion
  • Investigate real-world applications of static and kinetic friction
USEFUL FOR

Physics students, engineers, and anyone interested in understanding the principles of motion and friction in mechanics.

how do you figure out horizontal force necessary to move an object if the coefficient of kinetic friction is zero?
 
Physics news on Phys.org
It must be just big enough to over come the maxium static friction, then it will drop to the kinetic friction value of zero. But if kinetic friction is zero, it would probably be true that static friction is zero as well. But if you are moving, and you have zero kinetic friction, it takes zero force to keep it moving. You just need to give it an impulse to get it moving in the first place.
 
thx that helped...i actually figured it out on my own...
