Nissan Armada 2025-2026 Service and Repair Manual: Damage Diagnosis: Fundamental
What is force
Force causes the shape of objects and state of motion to change.
Equation that expresses force [F]
F= m + a
[m: mass in kg, a: rate of acceleration in m/s2]
The equation explains the factors that affect the force strength in a collision. The impact force is in relation to the mass and the rate of acceleration or deceleration of a vehicle.
In a collision a vehicle is damage is by the force which is applied on the vehicle. The force causes the shape of the vehicle to change as the force changes the state of motion it is in. There are 5 elements in force to consider.
The five elements of force
There are 3 main force elements, size, direction and application point. In damage diagnosis it is important to understand these as well by adding 2 more aspects of "number of impacts" and the "sequence of impact".
Please see below explanation in details:
| The Three Main Elements | 1. Force Size |
| 2. Force Direction | |
| 3. Force Application Point |
| Further aspects | 1. Size is shown through the length |
2. Direction by arrow  | |
| 3. Application point by tip | |
| 4. Force Number of Impact | |
| 5. Force Sequence of the Impacts |

What is Energy
Equation that expresses kinetic energy [EK]
EK = 1/2 ● m ● v2
[m: mass in kg, v: velocity in m/s]
The equation shows that the kinetic energy is proportional to the mass and the square of veloci ...
