Physics Notes

Vibration- any periodic pattern of motion Transverse- a cycle that is plumb line to the endure axis Longitudinal- a cycle that is parallel to the rest axis Torsional- a vibration that is more or less the rest axis Cycle- the total distance travelled during nonpareil meter out and back, staring(a) vibration Amplitude (A)- the displacement reply of the vibrating object from the rest position Period (T)- the time for oneness complete vibration Frequency (f)- the number of vibrations per second, measured in Hertz T = time /cyclesT = 1/fF = cycles/timeF = 1/T The general factor adverting pendulum motion is the length of the pendulum. Although the large insurance premium pendulum swings faster than the original pendulum, and the small amplitude pendulum is slower, they both receive the akin time to complete 10 cycles. Change in mass also does non affect the period in a pendulum because according to Newtons Law of Gravity, dryness negates any extra or slight weight in the mass. The length of the rope affects the period of the pendulum because it changes the intermediate the rolls travel through.

In phase- any two particles on the analogous side of the rest axis, the same distance from the rest axis, and vibrating in the same wariness Wavelength (?)- distance between two successive particles that argon in phase G,/,/,M,/,/,K,h,da,--,d,cm,mm,/,/,µ,/,/,n Example of constructive interference- waves in an ocean, laser, stereos? Example of wretched interference- acoustics, flashlight Universal Wave Equation- v = ?d/?tv = f? Fixed-end reflections- wave pulses that have their amplitude reflected inversely at fixed-ends Free-end reflections- wave pu! lses that have their amplitude reflected normally at a free end Phase shift- the relative position of the wave compared to a standard representation Standing wave- two waves of the same frequency and wavelength travelling in opposite directions, they do not transmit brawn (conditions, must be continuous,...If you want to pop off a plentiful essay, order it on our website: OrderEssay.net
