Natural frequencies represent inherent vibration tendencies of mechanical systems when disturbed
Determined by system mass and stiffness
Typically measured in Hertz (Hz)
Example: A guitar string's fundamental frequency
Mode shapes describe deformation patterns at specific natural frequencies
Unique for each natural frequency
Characterized by nodal points (stationary) and anti-nodes (maximum displacement)
Example: Vibration patterns of a circular drum head
