Property:Velocity

(diff) ← Older revision | Latest revision (diff) | Newer revision → (diff)

The rate at which an object's position changes with time. Has type speedThe type of this property is invalid, but it also can be a vector with a direction.

Definition

v = (Δ r) (Δ t)-1

Where v is the average velocity vector during the time interval Δ t, r is the position vector and t is the time.

Semantic Relation

Velocity is related to position and time.

[[frac::((times::(delta, Position),(times::(delta, Time))]]


And also a simple TEΧ like syntax.

[[=\frac{\delta \Position}{\delta \Time}]]


Plain ascii expression: "v = delta(r)/delta(t)" (1) and "(= v (/ (delta r) (delta t)))"

also in terms of Property:Momentum :

"v = p/m" (2) and "(= (v (/ p m)))"

Where:

Velocity is v and r = Property:Position t = Property:Time p = Property:Momentum m = Property:Mass
