Vocabulary
The process of changing position.
What is motion?
The rate of change of poition in which the same distance is traveled each second. It means to travel at the same speed over the entire distance.
What is constant speed?
The label for speed of an object if the time is measured in hours and the distance is measured in kilometers.
what is km/h or kilometers per hour?
on a speed-time graph, it is shown as a line that slants downwards towards the right side of the graph.
What is decreasing speed?
Distance d = 460 m
Time t = 4 s
Average Speed V= d/t
What is V?
90 m/s
A measure of the distance an object travels per unit of time. Normally labeled m/s.
What is speed?
Speed at a specific instant in time.
What is Instantaneous Speed?
"Eleven yards east of the field,' the field is considered to be a ____________________ for the location.
What is a reference point?
These boxes DO NOT have the same velocity.
What is C?
At 60 s they were at 300 m.
At 120 s that were at 600 m
Find the difference of each points. 120 - 60 = ? & 600 - 300 = ?
To find average speed you use distance divided by time. What is the average speed?
5 m/s
What is a reference point?
An object's distance and direction from a reference point.
What is position?
Velocity is different from speed because it includes this additional element.
What is direction?
What is the baseball players displacement?
A truck travels 300 miles and stops a few times along the way. The entire trip takes 5 hours. What is the average spped of the car?
60 mph
A measure of the change in velocity during a period of time.
What is acceleration?
The total distance traveled divided by the total time taken to travel that distance.
What is Average speed?
When an object slows down, it experiences this type of acceleration.
Negative Acceleration.
The three ways an object can accelerate.
What is increasing speed, decresing speed or changing direction?
In the graph, whar is the average speed of the moving object between 5 and 15 seconds?
20 m/s
The difference between the initial (first) position and the final position of an object. How far an object is in a straight line from it's reference point.
What is displacement?
The speed and the direction of a moving object.
What is Velocity?
One is about how much ground you've covered in total, while the other focuses on the change in position from the starting point to the ending point.
What is the difference between distance aand displacement?
Describing a position using two directions.
What is using two dimensions?
