AS1 1.4 Linear Motion Flashcards
1
Q
Define “displacement”
A
Distance of an object in a specific direction
2
Q
Define “Velocity”
A
The rate of change of displacement
3
Q
Define “average velocity”
A
Total displacement over time
4
Q
Define “acceleration”
A
Rate of change of velocity
5
Q
What is the equation for speed?
A
S = D/T
6
Q
What is the equation for velocity?
A
V = s/t
7
Q
What is the equation for acceleration?
A
A = V/T
8
Q
What are the 4 equations for motion in SUVAT?
A
V = u + at
S = 0.5(u + v)(t)
S = ut + 0.5(a)(t^2)
V^2 = u^2 + 2as
9
