Position Function:
s(t) =
∫v(t)dt, the antiderivative of velocity
Velocity function:
v(t) =
s’(t), the derivative of position, as well as ∫a(t)dt, the antiderivative of acceleration
Acceleration function:
a(t) =
v’(t), the derivative of velocity, as well as s’’(t), the derivative of position
A particle is moving left when…
v(t) < 0
A particle is moving right when…
v(t) > 0
A particle is not moving (at rest) when…
v(t) = 0
To find displacement of a particle with velocity v(t) from t = a to t = b, calculate this:
∫ab v(t)dt
To find total distance traveled by a particle with velocity v(t) from t = a to t = b, calculate this:
∫ab |v(t)|dt
