This applet simulate many particles slide down at different angle.

This applet simulate many particles slide down at different angle. How does this show the concept of Energy conservation: potential/kinetic energy ? with some explanation i should be able to make creative common it into something that schools can get students to explore themselves :) For your consideration ;) Title: Re: Energy conservation: potential/kinetic energyPost by: Fu-Kwun Hwang on June 17, 2008, 03:09:47 pm
The blue curves show blue(i)=(1/2)m*v
_{i}^{2}/(m*g), while black curves are black(i)=y_{i}.For each pair of curves, you will find blue(i)+black(i)=constant. So it is corresponds to conservation of energy. You can also draw curves for (1/2)m*v _{i}^{2} and m*g*y_{i}, and you will find the sum are the same for all the curves.What I did was just change the unit to be (m*g). So I draw (1/2)m*v _{i}^{2}/(m*g) and y_{i}-- vertical position of particle. |
