PHYSICS natural frequencies?
1) If an object is forced to vibrate at one of its natural frequencies, the phenomenon that occurs is called?
2) When an object vibrates at a natural frequency, the amplitude is?
3) When an instrument is making a sound, you can tell if the frequency is a natural frequency because the noise sounds?
4) The lowest frequency at which an object vibrates well is one of its natural frequencies. It has a special name; it is called the _________ frequency?
Comments
1. Resonance
2. Maximum
3. Loud
4. Fundamental
The answers to 1-3 are my best interpretation, as the questions are badly worded.
Natural Frequency Physics
stability of momentum. He sits on the swing. Neither him nor the swing are shifting. He leans returned. His midsection of gravity not decrease than the midsection of help of the swing.. its out of equilibrium. The gravitational tension appearing on him and the swing pass his midsection of gravity in the direction of the line that is going from the midsection of the earth to the suited of the swing. The stability of forces, and his muscle groups, have labored mutually to extend the momentum of him on the swing. there is kinetic potential interior the equipment, and momentum. If he keeps to be nevertheless then he will oscilate for a jointly as till friction losses sluggish and end the flow. He doesnt end. on the suited of the swing, he leans forward. His midsection of gravity is now even farther out of stability. The gravitational forces appearing on his physique, while they artwork to place him returned into equilibrium will develop up the swing.. it has much greater momentum, much greater kinetic potential to commerce. the finest assertion of the regulation is something like: sum(forces) appearing on equipment = derviative wrt time (mass * speed) or sum(F)=diff(m*v) or sum(F)=m*dv/dt + v*dm/dt or now and returned sum(F)=m*dv/dt = m*a
