Chapter 2: Mathematical Models Flashcards
Acceleration
The change of speed over time
Average speed
How fast something moves over a certain distance
Conceptual model
A written description or diagram based on ideas and observations that are used to describe how a process it object works
Deceleration
Occurs when change in speed or acceleration is in the negative direction
Dependent variable
The variable in an experiment that changes in response to choices made by the experimenter, plotted on Y axis
Free fall
The acceleration of a falling object under the influence of the earths gravitational force
Accelerate
To increase speed or change direction
Graphical model
Model that shows the relationship between two variables on a graph so that the relationship is easily seen and understood
Gravity
The attractive force that exists between any two objects that have mass
Independent variable
Variable in the experiment that is manipulated by the experimenter and that causes changes in the dependent variable - X axis
Instantaneous speed
The speed of an object at a specific point in its journey
Physical model
Models that are made out of materials and that can be touched and measured
Scientific model
A method of representing the relationship between variables
