SUMMARY

The discussion focuses on calculating the force of impacts on objects, specifically using examples involving a person colliding with a wooden fence and a TGV train colliding with an abandoned car. The calculations require knowledge of mass and velocity, as the force of impact cannot be determined solely from these variables without additional details about the collision dynamics. The examples provided illustrate the complexity of impact force calculations, emphasizing that factors such as distance and collision specifics are crucial for accurate results.

PREREQUISITES
  • Understanding of Newton's Second Law of Motion
  • Basic knowledge of momentum and energy transfer
  • Familiarity with units of measurement for mass (tons, pounds) and speed (km/h)
  • Concept of collision dynamics and impact forces
NEXT STEPS
  • Research Newton's Second Law of Motion and its application in collision scenarios
  • Learn about momentum conservation in elastic and inelastic collisions
  • Explore the use of simulation tools for impact force calculations
  • Study real-world applications of impact force analysis in engineering and safety design
USEFUL FOR

Physics students, engineers, safety analysts, and anyone interested in understanding the mechanics of collisions and impact forces.

1. For example. If you weigh 175lbs and you were

running into a wood fence at 7km/per hour how much

force is being applied the Wood fence?

Another Example. the TGV Train in France reached its

highest speed at 574km/per hour it weighs 415tons,

if this train were to collide with an abandon car on

the tracks how much force would be applied to the

abandon car on the tracks if the train were going

570km/per Hour and the Train weighs 415tons

(914,918lbs).

another example: A freight Train weighing 10,000

tons going at a speed of 50km/per hour were to hit

an abandon car how much force is being applied to

the car on the tracks?

The distance of the Fence is 40ft.

The distance of the Car is 100ft.

The force applied depends on the details of the collision. Given an impact velocity and masses, you can't find the force associated with a collision solely from that info.
