Motion
Question | Answer |
---|---|
Position (X) | An objects location at a given time |
Delta | used to indicate change |
Distance (d) | The amount of change of position between an initial position and final position D = X(f)- X(i) |
Reference point | A specific point used to monitor change of position |
Speed (V) | Distance an object travels in a unit of time v = d/t |
Final position | The position of an object at the end of motion |
Initial position | The position of an object at the start of a motion |
v=D/T | To calculate distance d = v*t To calculate time t = d/vto calculate time t = d/v |
Motion is... | Relative |
