Car Crashes

Car crashes happen thousands of time every year, and while they can be horrific they also offer an excellent look at momentum and impulse. Cars are extremely massive, and therefore have very large momentum's even at very low speeds. This is why innovations such as seat belts and air bags are so vital, they increase impulse to help the human body cope as huge amounts of kinetic energy that the vehicles possessed is transferred to them though extreme force. So if you ever think about ignoring that seat belt before you start driving, just do the math. I guarantee you'll put it on.

Seat belts are crucial! And now the safest cars have side air bags as well, as car designers understand that the longer the time of impact, the smaller the force felt upon the passengers, making the car safer.

Cars are designed so when they get in a collision the energy is spread out around the car so the driver doesn't feel it which minimizes the force felt by the driver
