How to convert from larger to smaller in metric unit
MULTIPLY BY 10
Uncertainty that lessens the doubt
ZEROING UNCERTAINTY
Uncertainty that uses own judgement to determine measurement
JUDGMENT UNCERTAINTY
Difference of measured value and true value
ERROR
Error that cannot be controlled
RANDOM ERROR
Error that happens when equipment is not calibrated or the user does not know how to use it
SYSTEMATIC ERROR
Which zeros can be considered significant
ZEROS SANDWICHED IN BETWEEN NON-ZERO DIGITS
TRAILING ZEROS
ZEROS WITH A BAR ON TOP
Quantity that is a combination of 2 or more fundamental quantities
DERIVED QUANTITY
Act of assigning a number to a particular property of an object
MEASUREMENT
What do you follow in multiplying or dividing significant figures
LEAST NUMBER OF SIGNIFICANT FIGURES
How close a given value is to an accepted standard
ACCURACY
Consistency of measurement
PRECISION
What do you follow in adding or subtracting significant figures
LEAST NUMBER OF DECIMAL PLACES
TRUE OR FALSE:
A coefficient of a scientific notation can be greater than 9.9
FALSE
If a scientific notation has a negative exponent, where will the decimal place move to, when converting to the larger value?
LEFT
If a scientific notation has a positive exponent, where will the decimal place move to, when converting to the larger value?
RIGHT
What does an angle represent in a vector
DIRECTION
The two parts of an arrow of a vector
LENGTH (MAGNITUDE)
HEAD (DIRECTION)

RESULTANT VECTOR
method that uses parallelogram and polygon methods
GRAPHICAL
method that uses Pythagorean theorem and trigonometric functions
ANALYTICAL
method that uses rectangular resolution or vector addition
COMPONENT
Method that uses motion sensors, force tables
EXPERIMENTAL
How fast an object is moving
SPEED
Rate at which an object changes its position
VELOCITY
Object’s speed at any given time
INSTANTANEOUS SPEED
Rate of change at a given direction and point in time
INSTANTANEOUS VELOCITY
Change in velocity
ACCELERATION
Object falls under the influence of gravity alone
FREE FALL
object moves in two dimensions
PROJECTILE MOTION
shape of the trajectory
PARABOLA
total horizontal displacement
RANGE
total vertical displacement (halfway)
MAXIMUM HEIGHT
motion of a body turning about an axis, each particle moves a circular path
ROTATION
time to reach a certain point in the trajectory
TIME OF FLIGHT
velocity of an object moving along a circular path
TANGENTIAL VELOCITY
changes in the linear speed
TANGENTIAL ACCELERATION
changes in the direction of the velocity
RADIAL/CENTRIPETAL ACCELARATION
Force that pushes away from the center
CENTRIFUGAL FORCE
Force that pushes toward the center
CENTRIPETAL FORCE
