A spring with original length L0 with a block at one end (another end is fixed)./htdocs/ntnujava/ejsuser/2/users/ntnu/fkh/springconstantfrictionforce_pkg/springconstantfrictionforce.propertiesFull screen applet or Problem viewing java?Add http://www.phy.ntnu.edu.tw/ to exception site list
You can use mouse to drag the block to change it position.
The spring will try to move back to it's equilibrium position.
Spring force F= -k *(L-L0)
There is a friction force between block and the floor, Fr= -mu*m*g;
There are three curves show x(t), vx(t) and K(t)=(1/2)m vx[sup]2[/sup](t).
Another spring will be drawn when you click [b]show L0 [/b] , you can drag it to change the original length L0.
