– 1 meter is defined as the distance travelled by light in a vacuum in 1/299,792,458 second. Speed of light is exactly 299,792,458 m/s.
LENGTH

SCIENTIFIC NOTATION
20
measure of how close a measurement to the true value/standard/known value. goal
ACCURACY
21

PRECISION
22
there are variations in the environment or in the measurement techniques during data measurement.
RANDOM ERROR
23
caused by faulty instruments or in the design of the experiment itself.
ex. Calibrate instruments
SYSTEMATIC ERROR
24
judging the accuracy of measurement
- when there is true value % error is calculated
PERCENT ERROR
25
precision
percent difference
26
the quantitative measure of how much your measured values deviate from a standard or expected value.
- disclaimer for our measured values and degree of accuracy and precision of a measuring system us related to it.
- It indicates the range of values within which the measurement is asserted to lie with some level of confidence. ∆A Uncertainty
UNCERTAINTY
27
smallest value that can be measured by the measuring instrument (smallest printed increment in t he measuring device)
- as a general rule, uncertainties should be reported with the same number of decimal places as the instrument used.
- uncertainty should be ± the least count.
LEAST COUNT
28
dimensionless and is obtained by dividing the absolute uncertainty by the numerical or measured value.
RELATIVE/ABSOLUTE UNCERTAINTY
29
numerical unit with direction, how much of a quantity
MAGNITUDE
30
physical quantities that have magnitude or size only. Without direction.
SCALE/SCALAR QUANTITY
31
physical quantities that have both magnitude and direction. Ex. acceleration, displacement, velocity, force, mass, etc.
VECTOR QUANTITY
32
physical property of a material or system that can be quantified or can be measured using members.
PHYSICAL QUANTITIES
33
magnitude and direction of R are then determined with a ruler and protractor.
GRAPHICAL METHOD
34
the vectors have the same direction, the resultant vectors magnitude is given by the scalar sum of the individual vectors magnitude.
ANALYTICAL METHOD
35
reverse process of vector addition. It is a process of describing a vector in terms of two perpendicular directions.
RESOLUTION OF VRCTORS
36
two or more direction
- resultant are simply the sum of the east-west and north-south components
- theta = angle bet. the resultant vector and the west axis.
COMPONENT METHOD
37
study the motion of objects, and the related concepts of force and energy, form the field called Mechanics.

38
deals with force and why objects move as they do.
DYNAMICS

WHY OBJECTS MOVE
KINEMATICS
40
rate at which distance is covered at a given time. It is a Scalar quantity and measured in unit m/s.
SPEED
41
rate at which displacement is covered at a given elapsed time. It is a Vector quantity and can also be measured in unit m/s.
VELOCITY
42
rate of change of velocity and is vector quantity. Any change in magnitude, in direction or both is considered a change in velocity. If an object moves from rest, that is acceleration since there have been a shift from 0 velocity (since the objects starts from rest) to a given velocity.
ACCELERATION
43
rate at which velocity changes. Like speeds can be positive or negative.
- If you decelerate to a complete stop in a car, so the acceleration is negative.
- Can be uniform or non-uniform.
AVERAGE ACCELERATION

can be described and analysed in two or three dimensions. To do this, we need to resolve motion into components and look at the straight-line motion in each dimensions separately.
