| Question | Answer |
|---|---|
| The object or point from which movement is determined is called the... | frame of referance |
| if movement is constant, it's impossible to... | determine whether you or another object is moving |
| movement can be measured only within... | referance to something that is assumed to be fixed in place |
| a change in position relative to a frame of referance is... | motion |
| motion is measured by... | distance and time |
| distance traveled by a moving object in a unit of time is... | speed |
| formula for speed: | distance/time |
| speed that doesn't change... | constant speed |
| average speed forumula: | total distance/ total time |
| speed at a given direction... | velocity |
| velocities that have the same direction, determine by... | addition |
| velocities that have different directions, determine by... | subtraction |
