| Question | Answer |
| units used for force | Newtons [n] |
| units used for pressure | newtons/centimeters2 [n/cm2] |
| units used for area | centimeters2 [cm2] |
| units used for distance | meters [m] |
| units used for speed | meters/second [m/s] |
| units used for reaction time | seconds [s] |
| units used for velocity | meters/second [m/s] |
| units used for length | meters [m] |
| units used for width | meters [m] |
| how are mass and weight different | mass is a measurement of matter and weight is a measurement of how gravity affects mass |
| define force | a push or a pull |
| whats the formula for pressure | p=f/a |
| as a mass increases an objects inertia ... | increases |
| define inertia | an objects resistance to a change in state of motion |
| why is newtons first law also called "the law of inertia" | because newtons first law is based on the property of inertia |
| what is newtons 1st law | an object in motion stays in motion, an object at rest stays at rest unless acted on by an outside force |
| define constant speed | a speed that doesnt change |
| define instantaneous speed | a speed at a particular instant in time |
| define average speed | total distance divided by total time |
| can average speed and instantaneous speed be the same? when? | yes when traveling at a constant speed |
| what is the distance between speed and velocity | velocity includes direction and speed does not |
| -whats the speed formula -re-write it, solved for time - re-write it, solved for distance | -s=d/t -t=d/s -d=t*s |
| as a driver increases his/her speed the minimum safe following distance ... ( increases or decreases) | increases |
| how does talking on a cell phone affect a drivers reaction time (increases it or decreases it) | increases it |
| what is the minimum safe following distance measuring | the distance traveled before a person reacts |
| when measuring a reaction time, what two events are we measuring the time between | when an event occurs and when a person reacts |
