It has both magnitude and direction, and in this case, it is given as a function of time in the xy-plane. Understanding velocity is crucial for determining how the position of the particle changes over time. Recommended video: Guided course 7:27 Escape ...
If that particle moves in a horizontal plane, then View Solution A 2.00 kg particle moves along an x axis in onedimensional motion while a conservative force along that axis acts on it. The potential energy U(x) associated with the force is plotted in Fig. 8-36a. That is, if the ...

As demonstrated in the previous section, the DEP force decreases as a particle moves away from the electrodes, meaning that lowering the channel height leads to a greater DEP force. Another force on the particles that varies with the channel height is the drag force. This force, which is cau...
