Electrostatics

... AC = V A - V C That is, the potential difference between two points is the difference in the voltage at the two points. If a displacement r is parallel to the electric field E, then V = - E r or E = - V / r Electric field lines and ...

Rotation

... have now defined angle, angular velocity, and angular acceleration exactly in the same way we defined their linear analogus, displacement, velocity, and acceleration: When we studied linear motion, we derived the "big three Kinematics ...

Periodic Motion

... F spring + mg F net = - k x' - mg + mg F net = - k x' Now this looks exactly like our pro-totypical equation with the displacement x' now being measured from the new equilibrium position. This means that everything we have ...

Ch 8, Gravity

...   6. A mass-and-spring simple harmonic oscillator has maximum kinetic energy A) at its equilibrium position B) when its displacement equals its amplitude C) half way between equilibrium and amplitude D) two-thirds of the way between ...

Motion in Two Dimensions

... need not be along one of the axes, of course. Consider a point P that is located by dis-placement vector r p1 with respect to reference frame 1 and located by displacement vector r p2 with respect to reference frame 2. And reference frame 2 ...

PHY 1150

... t = (36.1 m/s) t = s = 12.5 t = 12.5 s That tells us when . We can put that back into either displacement equation to determine where . The motorist's displacement, since it has only a term with time and not with time-squared, is the ...

Waves and Sound

... mass being transferred from one end of the rope to the other. This is the idea of wave motion. Amplitude is the maximum displacement from equilibrium. Wavelength is the distance between the waves. velocity = frequency x wavelength   ToC ...

Ch 7, Rotational Motion

... rotational effect.   Ex 7.25 How can the three bricks shown below be stacked so that the top brick has a maximum horizontal displacement from the bottom brick? For example, st-acking them like the dotted lines suggest would be unstable and ...

Motion in Two Dimensions

... with constant acceleration. Now we will throw the ball yet another time. This time we will look at its position or its displacement. These displacements come from the x- and y-co-mponent equations, x = x o + v xo t + 1 / 2 a x t 2 and y = y ...
