Reviewer Flashcards
It is a branch of science that describes matter, energy, space, and time at the most fundamental level
Physics
It is a process of writing very small and very large numbers using powers of 10
Scientific Notation
These are all the digits that are known accurately
Significant Figures
These are the units based on powers of ten and are used in scientific work and in European countries
Metric System of Units
These are basic types of units such as time, length, and mass
Dimensions
It is the number by which a quantity is multiplied or divided when it changes form
Factor
It is when one quantity increases/decreases, while the other quantity increases/decreases as well
Direct Proportion
It is when one quantity increases and the other quantity decreases
Inverse Proportion
It is a process of comparing quantities with standard
Measurement
It is about building conceptual and mathematical and comparing observations
Approximation
This is any quantity or property of a material or a system that can be quantified and measured by using numbers
Physical Quantity
These are the basic quantities that are independent of one another
Fundamental Quantities
These are the combinations of fundamental quantities
Derived Quantities
It is a measure of how close a measurement comes to the actual value of whatever is being measured
Accuracy
It is a measure of how close a series of measurements are to one another, irrespective of the actual value
Precision
It is the difference between the result of the measurement and the true value and it is a mathematical way to show the uncertainty in the measurement
Error
It is a result of unpredictable changes during data measurement and it is a chance difference between the observed and true values of something
Random Error
It usually comes from the measuring instrument itself. It is a consistent or proportional difference between the observed and true values of something
Systematic Error
It is the absolute value of the measured experimental value minus the accepted value divided by the accepted value, multiplied by 100%
Percent Error
These are quantities that can have magnitude, algebraic sign, and units but not a direction in space
Scalar Quantities
These are quantities with magnitude and have physical direction in space
Vector Quantities
It is the process of combining two vectors
Composition
It is a single sum of two or more vectors
Resultant
It is the science of describing the motion of objects using words, diagrams, numbers, graphs, and equations
Kinematics
It is a scalar quantity that refers to how much ground an object has covered during its motion
Distance
It is a vector quantity that refers to how far out of place an object is
Displacement
It is a scalar quantity that refers to how fast an object is moving
Speed
It is the speed at a particular moment in time
Instantaneous Speed
It is a vector quantity that refers to the rate at which an object changes its position
Velocity
It is the velocity at a specific instant of time
Instantaneous Velocity
It is a vector quantity defined as the rate of an object changes its velocity
Acceleration
