| Abstract: | The motion of slider exerted by a varying force was studied on an air track,using the falling of uniformly thin chains to change the force acting on the slider,the camera to record the slider's movement with the falling of the chains,and the dependence of the displacement and velocity on time was obtained by taking the frames of slider's movements. |

| Keywords: | air track variable force taking frame technique |
