(50 cards)
Drag Definition
the resistance to movement when one object passes through another object (liquid or gas). Always opposite the direction of movement
Shadow Equation
H/h = B/b Because of similar triangles.
Displacement
x2 - x1 the length and direction between the start position and end position of an object. (vector)`
When Changing Mediums
The frequency stays the same but the wavespeed and wavelength can change
The Equation For Gravity
Gravity = m * 9.8 meters per second squared
Period Definition (In terms of waves)
How many seconds does it take for one wave to pass
Refraction Definition
If light travels through a medium of a different optical density, the path of the light will bend. (Optical density means index of refraction, but put into practice)
Tension Definition
the cohesive force in a rope or string that pulls objects towards its center when the rope of strong is taught.
Viewing in Mirrors
The object will seem to be the same distance from the mirror as the "image" in the mirror will seem.
Scary Monster: Running Away Getting Slower
Negative Acceleration
Electric Circuit Definition
An electric circuit is a path along which electrons can travel
Voltage Definition
The difference in electrical potential between two points on a circuit. (kind of like the elevation difference between two points on a stream)
Scary Monster: Running Towards Getting Faster
Negative Acceleration
Resistance Definition
The slowing down of current in a circuit due to something impeding the flow
Frequency vs. Period Relationship (In terms of waves)
Frequency = 1/period and Period = 1/Frequency
Total Energy Rules
During a fall, TE never changes. E.g. if at the top GPE is 3 and KE is 0 then at the bottom KE is 3 and GPE is 0
Net Force Definition
Netforce = m *a
Crest Definition
The highest part of the wave
Dune Buggy Metaphor
When the first side of the front wheels of a dune buggy hit water, they slow down and since the other side is still going fast, then the buggy turns towards the water.
Velocity Definition
the displacement of an object during an interval of time. How fast and in what direction an object is traveling (vector)
Distance
the total length that an object travels, regardless of direction. (scaler)
Work Definition (From Energy)
Work occurs when you apply force over a distance.
How to set up a force diagram
F(Type of Force) (Object being acted on, Object acting on object)
Medium Definition (In Terms of Light)
Substance light is traveling through
Scary Monster: Running Towards Getting Slower
Positive Acceleration
Law of Reflection:
The angle of incidence = the angle of reflection
Terms for Refraction and Reflection Definitions (Not text based answer)

Compression Definition
The parts of a longitudinal wave that the waves are closer together than the average.
Wave Speed
How fast a wave travels away from its source.
When Not Changing Mediums...
The wave speed stays the same but you can change frequency and wavelength
Speed Equation
Speed = distance/ change in time s= d/t
Frequency (In terms of waves)
How many times a wave goes by in one second
Snell's Law
Index of Refraction of the first medium Sin of the angle of incidence = Index of Refraction of the second medium Sin of the angle of refraction
Acceleration
The rate at which an object is changing velocity (vector). How quickly an objects velocity is changing.
Umbra Definition
Full shadow; No view of the light source
Energy Definition
Energy is the capacity to do work.
Friction Definition
The resistance to an object
Trough Definition
The lowest part of the wave
Current Definition (Electric Form)
The amount of electrons traveling along the circuit
Scary Monster: Running Away Getting Faster
Positive Acceleration
Normal Force Definition
The supporting force acting perpendicular to a surface doing the supporting.
Inertia Definition
A measure of the resistance of an object to a change in motion (acceleration)
Forces at Angles Rules
The Sin of the angle the force is at times the number of newtons of force is how much force is applied either up or down. The same is true for Cos of the angle times the number of newtons of force applied for the x or horizontal direction.
Equation Velocity
Displacement / change in time
Force Rules
Force in same direction add Forces in opposite direction subtract Forces at angles have to be broken up into components
Penumbra Definition
Partial shadow; Can see part of the light source, but not all.
Weight Definition
The pull on an object towards an object with large amount of mass due to the force of gravity. On earth, always down.
What do Slopes on Position/Velocity Graphs Mean?
Slope = horizontal/vertical velocity
Force Definition
A push or pull that causes an object to change its motion (accelerate)
Scalar/scaler Definition
A number with no value. e.g.: 5 apples, or i am running at 5mph. Not saying 5mph to the west. Just 5mph
