3. Uniform and Non-Uniform Motion

Types of Motion

There are three types of motion:

• Translatory motion

• Rotatory motion

• Vibratory motion

Translatory Motion

• In translatory motion the particle moves from one point in space to another. This motion may be along a straight line or along a curved path.

• Motion along a straight line is called rectilinear motion.

• Motion along a curved path is called curvilinear motion.

• Example: A car moving on a straight road

Curvilinear Motion

• Rotatory Motion - In rotatory motion, the particles of the body describe concentric circles about the axis of motion. Rotatory Motion

• Vibratory Motion - In vibratory motion the particles move to and fro about a fixed point.
