Finding the Normal Force of a block

Click For Summary
SUMMARY

The discussion focuses on determining the normal force acting on a block sliding along a horizontal circular path inside a friction-free cone. The consensus is that the normal force (Fn) is greater than the gravitational force (mg) due to the centripetal acceleration required for circular motion. The participant concludes that option 3, which states that the normal force may be greater than mg, is correct. The relationship between normal force and gravitational force is influenced by the geometry of the motion and the absence of friction.

PREREQUISITES
  • Understanding of Newton's Second Law (F=ma)
  • Knowledge of circular motion dynamics
  • Familiarity with forces acting on objects in inclined planes
  • Basic concepts of normal force in physics
NEXT STEPS
  • Study the effects of centripetal force on normal force in circular motion
  • Explore the dynamics of objects on inclined planes
  • Learn about frictionless surfaces and their impact on motion
  • Investigate the role of diagrams in visualizing forces in physics problems
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and forces, as well as educators looking for examples of normal force in circular motion scenarios.

Homework Statement


And when the block is sliding along a horizontal circular path on the inside of a friction-free cone,the magnitude of the normal force (use the diagram)
1. is greater than mg, always.
2. is equal to mg.
3. may be greater than mg.
4. is less than mg, always.
5. may be less than mg.


Homework Equations


F=ma


The Attempt at a Solution


Fn=mg if horizontal plane which means when on a tilted plane, Fn<mg But in this case, the objects spins around which means it puts more force on the cone walls thus... more normal force. i believe it is 3. is this correct?

Can we see the diagram that you were using, or some crude replica of it?
