This simulation show The relations between acceleration, velocity and displacement in simple harmonic motion{(b. investigate the motion of an oscillator using experimental and graphical methods) and (g. describe with graphical illustrations, the changes in displacement, velocity and acceleration during simple harmonic motion)}, right ? ??? Thanks

Yes! relations between acceleration, velocity and displacement in simple harmonic motion can be observe in the inquiry learning virtual lab.

experimental method is the oscillator moving in SHM

graphical corresponding graphs total there are 7 of them.

to describe can used the wiki explanation:

In physics, simple harmonic motion (SHM) is the motion experiences a single force that is directly proportional to the displacement x and points in the opposite direction.

the equation model is a = - w[sup]2[/sup]x

a acceleration

w omega is angular velocity of SHM

x displacement of object in SHM from the equilibrium position

let me know what you need to understand in SHM, i think i will create an exercise to let u try with the applet ;D
