# Collision
|
|
|
|
A collision is a broad term that describes any event where two or more bodies exert forces on each other for a relatively short time.
|
|
|
|
The [[Hertz Law]] describe the contact between two elastic solids.
|
|
|
|
There is also [[Inelastic Collisions]].
|
|
|
|
Collision analysis often emphasizes momentum exchange
|
|
# Impact
|
|
|
|
An impact is a type of collision with a high force over a short duration.
|
|
|
|
(see [[Impact Models]])
|
|
|
|
Impact analysis considers material deformation and damage
|
|
|

# Shock
|
|
|
|
A shock is a sudden acceleration caused by various events, including impacts.
|
|
Key characteristics of shock include:
|
|
|
|
- A transient physical excitation
|
|
- Extreme rates of force with respect to time
|
|
- Measured as a vector with units of acceleration (often in multiples of g)
|
|
|
|
Shock analysis concentrates on acceleration and its effects on structures |
