|
|
|
What is the formula for speed?
|
s=d/t |
|
|
What is constant speed?
|
it is the rate of change of position in which the same distance is traveled each second.
|
|
|
What is Instantaneous speed?
|
it is a speed at a specific instant in time |
|
|
What is average speed?
|
it is the total distance traveled divided by the total time taken to travel that distance.
|
|
|
What is Distance-Time graph?
|
is a graph that shows a comparison between distance and time.
|
|
|
How is constant speed shown as?
|
it is shown as a straight line in a Distance-Time graph.
|
|
|
What can you use distance-time graph?
|
to compare the motion of two different objects. |
|
|
What is velocity?
|
it is the speed and the direction of a moving object.
|
|
|
How can the velocity of an object be represented?
|
by an arrow
|
|
|
How is greater speed shown?
|
by a longer arrow
|
|
|
What does the arrow point to?
|
it points in the direction of the object's movement.
|
|
|
When does the velocity change?
|
When the speed of an object changes when the direction that the object moves changes or when both the speed and the direction change.
