velocity time graphs. Flashcards
1
Q
what does a velocity time graph show?
A
it shows how the velocity (or speed) of an object changes over time.
2
Q
what does a line going up in a VTG indicate?
A
constant acceleration.
3
Q
what does a horizontal line in a VTG indicate?
A
constant velocity (no acceleration)
4
Q
what does a line going down in a VTG indicate?
A
constant deceleration.
5
Q
what does gradient =
A
gradient = rise / run
6
Q
how can the distance of an object be found in a velocity time graph?
A
by determining the area beneath the graph. area = (1/2) x base x height
7
Q
v2 = u2 + (2 × a × s)
A
(final speed)2 = (initial speed)2 + (2 × acceleration × distance moved)
