| we use these to slow down a car | brakes |
| this would reduce the friction in a squeaky hinge | oil |
| a vehicle that uses air to reduce friction | hovercraft |
| friction caused by air | air-resistance |
| new cars are tested inside one of these | wind- tunnel |
| make a shape smooth to reduce drag | streamline |
| Foece which pullds you towards the ground | Gravity |
| your mass multiplied by the gravity field strength | weight |
| Measured in Kilograms | mass |
| these arrangement of forces means no acceleration | Balanced |
| you get this if two surfaces rub against each other with a lot of friction | heat |
| to change a car's speed you need to apply a .. | force |
| It is difficulkt to drivre in these conditions | icy |
| Curlers make the ice smooth by | sweeping |
