**Kinematics**

Kinematics is the branch of mechanics that deals with the motion of objects without considering the forces that cause the motion. In MAE 345LR, you will learn about the following concepts related to kinematics:

**Definition**

Kinematics is the study of motion of objects without considering the forces that cause the motion.

**Types of Motion**

There are three types of motion: translational, rotational, and general motion.

**Coordinate Systems**

Coordinate systems are used to describe the position, velocity, and acceleration of an object.

**Relative Motion**

Relative motion describes the motion of an object with respect to another object or a reference frame.

**Kinetics**

Kinetics is the branch of mechanics that deals with the forces that cause motion. In MAE 345LR, you will learn about the following concepts related to kinetics:

**Definition**

Kinetics is the study of the forces that cause motion.

**Forces and Moments**

Forces and moments are used to describe the effects of external forces on an object.

**Newton’s Laws**

Newton’s laws describe the relationship between an object and the forces acting upon it.

**Work and Energy**

Work and energy are used to describe the motion of an object and the effects of external forces on it.

**Vibrations**

Vibrations are a common phenomenon in mechanical and aerospace systems. In MAE 345LR, you will learn about the following concepts related to vibrations:

**Definition**

Vibrations are oscillations of a mechanical system about an equilibrium position.

**Free Vibrations**

Free vibrations occur when a mechanical system vibrates without any external forces applied.

**Forced Vibrations**

Forced vibrations occur when a mechanical system vibrates due to an external force applied to it.

**Damped Vibrations**

Damped vibrations occur when a mechanical system loses energy due to friction or other damping mechanisms.

**Control Systems**

Control systems are used to regulate the behavior of a mechanical system. In MAE 345LR, you will learn about the following concepts related to control systems:

**Definition**

A control system is a system that regulates the behavior of a mechanical system.

**Feedback Control**

Feedback control is a type of control system that uses feedback from the output of the system to adjust the input.

**Transfer Functions**

Transfer functions are used to describe the relationship between the input and output of a control system.

**Stability Analysis**

Stability analysis is used to determine the stability of a control system.
