Question | Answer |
---|---|
reference point | a point against which direction is measured |
displacement | the distance an object travels plus direction from the starting point |
vector quantity | a physical measurement that contains both magnitude and directional information |
scalar quantity | a physical measurement that contains only magnitude |
average speed | the ratio of the total distance traveled to the total time of the trip |
Instantaneous speed | the rate at which an object is moving at a given moment in time |
Acceleration | the time rate of change of an object's velocity |
two or more displacements can be combined by what method? | graphing |
equation of acceleration | final velocity - initial velocity divided by time |
when traveling in the same direction, relative speed: | speed of object 1 - speed of object 2 |
velocity | how quickly an object moves + direction |
when traveling towards each other, relative speed: | speed of object 1 + speed of object 2 |
speed equation | distance divided by time |
