1. The tendency for a stationary object to remain at rest, and for a moving object to continue at the same speed is called: A momentum B friction C inertia |

2. Which vehicle - a motorbike or a truck - would have the greatest inertia? A they are the same B the motorbike C the truck |

3. If a car brakes suddenly, the first movement of the passengers is to: A continue to move forward at the same speed B be thrown back into the seat C move backwards as the seat belt tightens |
