Force Calculations: Fnormal, Fg, Ffriction, Fapplied - SOLVED

Click For Summary
SUMMARY

In force calculations involving horizontal motion, the normal force (Fnormal) is equal to the gravitational force (Fg) acting on the object. When an object is pushed horizontally, static friction (Ffriction) equals the applied force (Fapplied) only up to the point of impending motion. Once the object is in motion, kinetic friction remains constant and is proportional to the normal force. This distinction is crucial for understanding the dynamics of objects on flat surfaces versus inclined planes.

[SOLVED] Force Calculations

If an object is being pushed horizontally, does Fnormal always equal Fg? And Ffriction only equals Fapplied if it's at a constant velocity? I think that's how it goes, but I'm a little unsure.

Thanks!

Yes if the force on an object is horizontal then the normal force will simply be the weight of the object. If it is on an incline then that's another matter altogether. Static friction equals the applied force to a certain point but kinetic friction is pretty much constant and proportional to the normal force.
