Physics Flashcards
What is deceleration
Acceleration in the direction opposite to velocity which results decrease
What is acceleration
Rate of change in velocity over time
What is centripetal acceleration
Acceleration directed toward a center in a circular motion or rotation
What is instantaneous acceleration
Acceleration at a specific point in time
What is accuracy
Degree a measured value agrees with correct value of measurement
What is an analytical method
A method for determining the magnitude and direction of a resultant vector using trigonometric theorems
What is approximation
Estimation of value based on prior experience and reasoning
What is air resistance
Frictional force on matter traveling through air
What is the value of air resistance when solving basic physics problems
Zero
What is a carrier particle
A fundamental particle of nature that is surrounded by a characteristic force field
What are photons
Carrier particles of the electromagnetic force
What is commutative
Interchangeability of order in a function
What are processes of commutative
(1) Addition (2) Subtraction (3) Product (4) Quotient
What is a vector component
The part of a vector which points in a direction
How are 2D vectors expressed
Sum of two vertical and horizontal vector components
What is a conversion factor
A ratio expressing how many units are equal to another unit
What is deformation
Change in shape due to the application of force
What is shear deformation
Deformation perpendicular to the original length of an object
What is a dependent variable
A variable that is being measured
Where are dependent variables plotted
Usually the y-axis
What is an independent variable
A variable that is being referenced
Where are independent variables plotted
Usually the x-axis
What are derived units
Units that can be calculated using algebraic combinations of the fundamental units
What is direction
Orientation of a vector in space
