3 - Motion Flashcards
1
Q
What is the equation of speed?
A
v = change in x/change in t.
2
Q
How are stationary, constant speed and varying speed shown on a distance-time graph?
A
Horizontal,sloped,wiggly.
3
Q
Define instantaneous speed.
A
Speed at a specific instant in time.
4
Q
How are stationary, constant speed, varying and backwards speed shown on a displacement-time graph?
A
Horizontal, sloping, curved, negative gradient.
5
Q
How are stationary, constant inc acceleration, constant dec acceleration and varying velocity shown on a velocity-time graph?
A
Horizontal, sloping up, sloping down and squiggly line.
6
Q
What do the letters of suvat stand for?
A
displacement
initial velocity
final velocity
acceleration
time
7
Q
What are the 4 suvat equations?
A
v = u + at
s = ut + 1/2at^2
s = 1/2(u + v)t
v^2 = u^2 +2as
