1
New cards

Initially

t = 0

2
New cards

At rest

v(t) = 0

3
New cards

Particle moving right (forward)

v(t) > 0

4
New cards

Particle moving left (backward)

v(t) < 0

5
New cards

Average velocity on [a, b]

s(b) - s(a) / b - a

6
New cards

Instantaneous velocity at time t

v(t) = s’(t)

7
New cards

Acceleration at time t

a(t) = v’(t) = s’’(t)

8
New cards

Velocity is increasing

a(t) = v’(t) > 0

9
New cards

Velocity is decreasing

a(t) = v’(t) < 0

10
New cards

Speed

|v(t)|

11
New cards

Speed is increasing (accelerating)

v(t) and a(t) have the same signs

12
New cards

Speed is decreasing (decelerating)

v(t) and a(t) have the different signs

13
New cards

Particle is farthest left (right)


Compare positions (x-values) at endpoint and at relative minima/maxima
