Description
This model applies for a point particle subject to a constant acceleration that is either parallel to or antiparallel to the particle's initial velocity. It is a subclass of the One-Dimensional Motion (General) model defined by the constraint da/dt = 0.
Prerequisite Vocabulary
- position (one-dimensional)
- velocity (one-dimensional)
- acceleration (one-dimensional)
Model SpecificationSystem Schema
Internal Constituents: None. Object must be treated as a point particle.
External Agents: Some constant external influence must be present which produces the acceleration.Descriptors
Object Variables: None.
State Variables: Time (t), position (x) , and velocity (v) are possible state variables. Note that in some cases only two of the three possible state variables will be needed.
Interaction Variables: Acceleration (a).Laws of Interaction
Acceleration must be a constant.
