| m/s | unit for speed |
| mass | as this increases, inertia increases |
| motion | the state at which an object's distance from position is changing |
| seconds | unit for time |
| meters | unit for distance |
| frame of reference | point from which movement is determined |
| distance | measurement from one point to the next |
| distance | scientific unit is meters |
| displacement | distance and direction of object's change in position |
| speed | distance divided by time |
| speed | units are m/s or km/hr |
| constant speed | speed doesn't change |
| changing speed | result of speeding up or slowing down |
| average speed | total distance traveled divided by total time of travel |
| instantaneous speed | result of speedometer reading |
| time | units are seconds or hours |
| meters, kilometers, centimeters, millimeters | units for distance |
| F: s = d/t W: 12.75 km / 0.50 hours A: 25.50 km/hr | The car traveled 12.75 km down the road in 0.50 hours. Determine average speed. |
| F: displacement same direction = add, W: 2.00 km + 3.50 km + 6.30 km A; 11.80 km west | Determine displacement of Mary participating in triathalon by swimming 2.00 km west, then runs 3.5 km west, then gets on a bike traveling 6.30 km. |
| units for distance | meters, kilometers, centimeters, millimeters |
