velocity-time graphs Flashcards
1
Q
In a velocity time graph, what does a straight diagonal line mean?
A
That the object travel with increasing speed
2
Q
Fill in the blank. The steeper or greater the gradient of the straight line, the …….. the acceleration.
A
greater
3
Q
In a velocity-time graph what do straight lines with a negative gradient (sloping down) mean?
A
That the object is decelerating
4
Q
In a velocity-time graph, what does a horizontal (flat) line mean?
A
That the object is moving at a constant velocity
5
Q
Is speed scalar or vector?
A
scalar
6
Q
Is velocity scalar or vector?
A
Vector
7
Q
How do you find acceleration on a velocity time graph?
A
Rise over run. It is the gradient of the line.
8
Q
How do you find the distance in a velocity-time graph?
A
From the area under the graph.
