Across
- 2. this occurs when a driver is moving too fast on a wet road
- 5. running shoes aim to help athletes do this quickly
- 7. These provide pathways for water to pass beneath the tire as it rolls over a wet road
- 10. some material of this element is able to be "near-frictionless" with a coefficient of friction of 0.001
- 11. if you brake, this system will keep you safe
- 12. don't forget to wear this when in a car
- 15. what type of zones on cars help reduce injuries in accidents
- 18. this type of 'steering' occurs when the force of friction on the front wheels of a car is not enough to prevent the car from travelling in a straight line during a turn
Down
- 1. Uses computers and censors to help driver maintain control of vehicle during acceleration
- 3. this feature of a seatbelt pulls in on the belt when a crash is detected
- 4. what type of gas is the product of the reaction in an airbag
- 6. these devices allow surfaces to slide or roll across each other while reducing the force of friction
- 8. Generally the force of friction is not affected by the amount of surface are in contact with a surface, this material is an exception to that
- 9. leather grip's on golf clubs increase this type of friction on the players hand
- 13. material with a low coefficient of friction, used in cooking
- 14. this technique for prosthetic development closely monitors grip of the hand and makes adjustments to the force of the mechanical arm
- 16. these trains use magnetic bearings
- 17. used in crash tests to collect data and accurately simulate a person
