1st order modelling 1: Mass-damper

Vocabulary flashcards covering the concepts of first-order modeling, mass-damper arrangements, and force balance equations based on the lecture by Anthony Rossiter.

Mass-damper system

A simple mechanical example, such as a vehicle where the engine provides a drive force and wind or road provide friction or drag, resulting in a $1^{st}$ order differential equation.

Parallel Arrangement

A configuration where the force is divided between various components that share the same displacement or velocity.

Series Arrangement

A configuration where the same force goes through several components which have independent movement.

Damper with a fixed point

A physical damper component where only one end moves while the other remains stationary.

Floating damper

A physical damper component where both ends can move.

$1^{st}$ order ODE

A first order ordinary differential equation which represents the simple model of behavior derived from a mass-damper system.

Force balance

The analysis used to determine the overall model of behavior by accounting for drive force, mass acceleration, and drag.

Friction/Drag

In vehicle dynamics, it is modeled as damping that is considered to be independent of location and not based on a specific physical component.

Steady-state behaviour

The focus of introductory modeling videos, contrasted with this session's focus on dynamic behavior.

Newton's law

The fundamental principle used to analyze systems that may appear to be in series but do not satisfy requirements for carrying the same force and having independent velocities.
