Physics Final S2 Vocab (copy)

any object submerged in a fluid experience an upward buoyant force equal in magnitude to the weight of the fluid displaced by the object

the pressure of a fluid decreases as its velocity increases

upward force that keeps objects afloat

the magnitude of force on a surface per unit area

pressure applied to a fluid in a closed container is transmitted equally to every point of the fluid and to the walls of the container

every particle flows is in the same direction/along the same path.

vibration of a system where some points remain fixed

lowest and the most basic frequency of vibration of a standing wave

Quality of sound

a phenomenon that occurs when the frequency of applied force matches the natural frequency which leads to a larger amplitude of vibration
