100
A branch of science that involves the study of the physical world: energy, matter, and how they are related.
What is Physics
100
A comparison between an unknown quantity and a standard.
What is a measurement?
100
The factor that is changed or manipulated during the experiment.
What is an independent variable?
100
A series of images showing the positions of a moving object at equal time intervals.
What is a motion diagram?
100
How far the object is from the origin.
What is distance?
200
This is used when converting units from something like meters/sec to miles/hour.
What is a conversion factor?
200
The degree of exactness of a measurement.
What is precision?
200
The factor that depends on the independent variable.
What is the dependent variable?
200
A simplified version of a motion diagram in which the object in motion is replaced by a series of single points.
What is a particle model?
200
Quantities that have both magnitude and direction.
What is a vector?
300
These are the valid digits in a measurement.
What are significant digits?
300
How well the results of a measurement agree with the "real" value.
What is accuracy?
300
A linear line drawn as close as possible to all the data points.
What is the line of best fit?
300
This system tells you the location of the zero point of the variable you are studying and the direction in which the values of the variable increase.
What is a coordinate system?
300
Quantities that are just numbers without any direction.
What are scalars?
400
Making observations, doing experiments, and creating models or theories to try to explain your results or predict new answers.
What is the scientific method?
400
The apparent shift in the position of an object when it is viewed from different angles.
What is a parallax?
400
This relationship results when one variable increases while the other variable decreases.
What is an inverse relationship?
400
The point at which both variables have the value zero.
What is the origin?
400
When data is graphed by plotting the time data on a horizontal axis and the position data on a vertical axis.
What is a position-time graph?
500
A rule of nature that sums up related observations to describe a pattern in nature.
What is scientific law?
500
This system offers an illustration of accuracy and precision in measurement.
What is Global Positioning System?
500
This relationship results when one variable depends upon the the square of another.
What is a quadratic relationship?
500
The separation between an object and the origin.
What is position?
500
The position at a particular instant.
What is the instantaneous position?
