AC is the type of current you get from wall outlets; the current switches direction 60 times a second (60 Hz current). With AC, we begin the study of circuits with non-linear circuit elements such as capacitors, inductors and transformers, which are the back-bone of analog and power electronics.

We are now going to explain why objects move or do not move. We do so by using the concept of force. In this chapter we consider the basic techniques of free-body diagrams, the normal force, and the forces of weight and tension.

Common conventions are to call Earth (and any conductors connected to Earth) zero Volts or to set the zero of electric potential at a distance very far away (infinity) from the charge distribution.

What is the average x acceleration of the ball during the interval of the first bounce, that is from t=0.85 s to t=0.95 s? At t=5.0 s, what is the direction of the velocity vector and what is the direction of the acceleration vector for the red point?

The relative magnitudes of the individual harmonics are different for the clarinet and the trumpet, which is why the two instruments sound different even when they play the same note. Vary the speed of the source from zero to the speed of sound and then to the maximum value allowed by the slider.
