this creates a push or pull on an object
force
any change in velocity (speeding up, slowing down, or changing direction)
acceleration
What is the Law of Conservation of Energy?
Energy cannot be created or destroyed, only transformed.
the amount of matter in an object
the describes how tightly packed matter is:
The formula is D=M/V
Density
the tendency of an object to resist changes in motion
inertia
the ability to do work
energy
The height of a wave as it relates to loudness in sound
amplitude
What is weight?
Archimedes' Principle
Daily double if you can tell me an interesting fact about Archimedes
Buoyant force equals the weight of the fluid displaced.
(Assasinated, "Eureka", mathemitician, bathtub)
a force that resists motion when two objects rub together
friction
stored energy
potential energy
The distance between two peaks of a wave
Wavelength
Explain buoyant force
the upward force exerted by a fluid on an object
When an object is less dense than the fluid it displaces and floats
Positive buoyancy
force of attraction between two objects that have mass
gravity
energy of motion
kinetic energy
this describes how many waves pass a point in a certain amount of time
Frequency
Any substance that can flow (liquids and gases)
fluid
When an onect's weight equals the buoyant force and stays suspended in fluid.
neutral buoyancy
speed in a specific direction
Formula: W = f/d
work
The substance (solid, liquid, gas) a sound wave travels through
medium
Describe displacement
the volume of fluid pushed out of the way by an object
When an object is more dense than the fluid it displaces and sinks
Negative buoyancy
