What occurs when vibrations through an object match the object's natural frequency?
Any object in absence of external force vibrates with it's natural frequency. When the frequency of the external forced vibration matches the object's natural frequency, we say that resonance has occurred. In this situation the amplitude of the object's oscillation becomes larger. How much larger depends on the amplitude of the forced vibration.
What physics principle is used when pumping your legs in rhythm with the natural frequency of a swing?
Resonance - when pumping a swing in rhythm with its natural frequency, it produces larger amplitudes.(def. - occurs when the frequency of a vibration forced on an object matches the object's natural frequency and a dramatic increase in amplitude occurs)
What are the differences between free vibrations and forced vibrations?
a body A capable of vibrating, is made to vibrate another vibrating body B, Astarts vibrating with the natural frequency of B. now the vibrations of Aare called forced vibrations. example;vibration on sonameter.
When a forced vibrations matches an object's natural frequency does it resonate?
Yes!
What are you conclusions about the phase relationship between the driver and the oscillator below and above resonance?
For small frequency of forced oscillation , the phase angle between the forced oscillator and driver is nearly zero . As the driving frequency increases the phase angle increases and is equal is PI/2 ,when both the frequencies (frequency of force and frequency of system for oscillation) are equal. For very large frequency of driver , they are out of phase.
What is the relationship between forced vibration and resonance?
Forced vibration occurs when an object is made to vibrate by another vibrating object. Resonance occurs when frequency of a vibration forced on an object matches the objects natural frequency Appyed force to a vibrating system and then removing the source energy.

What is difference between forced vibration and damped vibration?
Forced vibration: If a system is subjected to an external force, the resulting vibration is known as forced vibration if the frequency of the external force coincides with one of the natural frequencies of the system, a conditions known as resonance occurs (large oscillation). Failures of such structures as building, bridges, turbines and airplane wings have been associated with the occurrence of resonance.Damped vibration: Ifanyenergy is lost or dissipated in friction or other resistance during oscillation, the vibration is damped vibration.
When you tap a glass with a little water in it It has a high pitch when you tap a glass with water filled to the top it has a low pitch why does this happen?
Glass has a natural frequency at which it vibrates, known as its resonant frequency. If you put energy into the substance at its resonant frequency, you will force it to vibrate or resonate (resonance is a forced vibration). So, tapping imparts energy to the glass molecules and causes them to resonate. This motion sets up a wave of vibration traveling through the glass. The vibrating glass causes air molecules to vibrate similarly. The vibrating air molecules are the sound wave that you hear (the frequency or pitch of the sound wave is the same as the resonant frequency of the glass). As the resonant wave moves through the glass, it moves the water molecules with it, creating a wave of water that you can see near the edge of the glass. The dragging water molecules effectively increase the mass (both the water and the glass molecules) and reduce the energy of the wave traveling through the glass. When the energy is reduced, so is the frequency of the wave in the glass, which is reflected in the pitch of the sound wave that you hear. In simpler terms, when you tap a glass with a lot of water in it, there are fewer vibrations because they have more trouble traveling through the higher mass. Thus, the lower pitch.
Difference between free vibrations and forced vibrations?
On free vibration the beam or structure is not suffering influence of forces (Beam on space). In forced vibration the structure is under presence of force example bridges. Later on will you discover the free vibration is important to obtain natural frequencies and mode shapes. the difference b\w forced and free vibration can be understand by the examples.............a) the vibration of a pendulum is free vibration which needs no external force to vibrate. b) the vibration of a machine like a drill is forced vibration which needs an external force to vibrate.
Why does a struck tuning fork sound louder when its handle is held against the table?
That would cause a forced vibration; the tuning fork will make the table vibrate, or part of it, and thus, there is more surface to make the air vibrate.That would cause a forced vibration; the tuning fork will make the table vibrate, or part of it, and thus, there is more surface to make the air vibrate.That would cause a forced vibration; the tuning fork will make the table vibrate, or part of it, and thus, there is more surface to make the air vibrate.That would cause a forced vibration; the tuning fork will make the table vibrate, or part of it, and thus, there is more surface to make the air vibrate.
