Example of Force on Car
(This initial example is cast in U.S. common units because most U.S. readers can make comparisons to known forces more easily in those terms. The calculation provides the results in SI units as well.) Vary the parameters of the collisionNote: these examples of forces during collisions use the average of force over distance rather than the average over time. The profile of force during a collision such as that of a car with a tree can be complex, whether expressed in terms of time or distance. The average over distance is used here because of its relationship to the conservation of energy and the work-energy principle.

Calculation of Force on Car
You may change any data value. Clicking outside the box will then initiate a calculation of the impact force and conversion of the data value to the other types of units. Discussion of car crash scenario |
