Kinematics Flashcards
1
Q
What is displacement?
A
Displacement is the change in position,
∆x = x2 - x1
2
Q
What is speed?
A
Speed is a scalar quantity,
|v| = distance / time
3
Q
What is average velocity?
A
Velocity is the rate of change of displacement over time:
v = ∆x / ∆t
4
Q
What is instantaneous velocity?
A
The instantaneous rate of change of displacement over time,
v = lim_(∆t->0) ∆x/∆t = dx/dt
5
Q
What is average acceleration?
A
Acceleration is the rate of change of velocity over time,
a = ∆v / ∆t
6
Q
What is instantaneous acceleration?
A
The instantaneous rate of change of velocity over time:
a = lim_(∆t->0) ∆v/∆t = dv/dt
