In order to be successfully in applying Newton's second law to a mechanical system,

we must first be able to recognize all the forces acting on the system.
This java applet shows the free-body force diagram for a block sits on an inclined plane.

Usage:

theta

mg)

Under which conditions the normal force becomes zero (vanish)?

F=0.

When will we have a maximum net force?

Then we will know the friction between the block and the incline plane.

Notice: there is a maximum value.

NF.

Dear Sir:FU-Kwun Hwang.

I am a High School teacher from La Corunha , Spain ( Galicia ) near
Portugal.

I realy like yours appelets of Java and I am used to work with them in
my classes.
If you don`t mind I would like to know if is posible for you to do one
about this:
A force pulling a block on a slope, and showing the forces growing when
you aplay diferents pulls.
Also it would be a plesure if you could do another one: a block moving
in horizontal , changing the force angles when you pull the block, and
at the same time showing the celerity of the block. The most eficient
angle to move is when the tg (angle) = coefficient of rubbing

Sorry for my english

I?m very pleased for having found your work, amazed work, which is very
useful for my students and also for me.
Before all, thank you very much for your work and help.

Pepe Villasuso
