Describing Movement Flashcards
In distance-time graphs, what usually is the x-axis?
Time (because it’s an IV)
In distance-time graphs, what usually is the y-axis?
Distance (because it’s a DV)
On a D-T graph, what feature indicates that the object is stationary?
The graph is straight and horizantal
On a D-T graph, what is the object doing when the graph is increasing in distance while also increasing in time?
The object is moving forward
What feature of a D-T graph signifies that the object is moving backwards?
The graph is decreasing in distance while increasing in time.
The __ the graph is, the faster the object is. Fill in the blank.
Steeper
What does a steep line indicate? (Be specific)
It indicates that there is a relatively faster increase in distance in terms of time.
What does a less steep (gentle) line indicate?
It indicates that there is a relatively slower increase in terms of time.
a. If an object travels 2000m in 200s, then where should you plot the dot?
b. How fast is this object traveling at?
a. x=200(s) and y=2000(m)
b. 10m/s
If the graph is curved and the “corner” of the graph is in the top left, what is the object doing?
The object is slowing down whilst going forwards.
If the graph is curved and the “corner” is in the bottom right, what is the object doing?
The object is speeding up whilst moving forwards.
If the graph is curved and the “corner” is in the top right, what is the object doing?
The object is speeding up whilst going backwards.
If the graph is curved and the “corner” is in the bottom left, what is the object doing?
The object is slowing down whilst going backwards.
In a D-T graph, what is the object doing if the graph is straight and its distance and time are both increasing?
The object is moving forwards at a constant speed.
In a D-T graph, what is the object doing if the graph is straight and its distance is decreasing while its time is increasing?
The object is moving backwards at a constant speed.
