Motion
For 8th grade science, includes motion, speed, reference point, acceleration, balanced forces and unbalanced forces
|
| A | B |
|---|
| motion | Distance from another object is changing. |
| reference point | a place or object that can be used to determine if an object is in motion |
| should reference point be moving | no reference point is stationary |
| Speed = | Distance/Time |
| Units to express speed | m/h or m/s or km/min |
| Acceleration | rate at which velocity is changing |
| Force | Push or pull exerted on an object |
| Does every force cause acceleration | no every force does not |
| Unbalanced forces | cause motion |
| Balanced forces | do not cause motion |
| a unit of force | newton |
| it has wheels | rolling friction |
| no wheels | sliding friction |
| resists change in motion | inertia |
