Speed by Initial and Final Values

The speed of an object is the rate of change of its position.

The speed is the displacement of an object divided by the time.

Formula

(QuantityVariable[Subscript["v", "f"], "Speed"] + QuantityVariable[Subscript["v", "i"], "Speed"])/2 == (QuantityVariable[Subscript["x", "f"], "Length"] - QuantityVariable[Subscript["x", "i"], "Length"])/QuantityVariable["t", "Time"]

symbol description physical quantity
vf final speed "Speed"
vi initial speed "Speed"
t time "Time"
xf final position "Length"
xi initial position "Length"

Examples

Get the resource:

In[1]:=
ResourceObject["Speed by Initial and Final Values"]
Out[1]=

Get the formula:

In[2]:=
FormulaData[ResourceObject["Speed by Initial and Final Values"]]
Out[2]=

Use some values:

In[3]:=
FormulaData[ ResourceObject[ "Speed by Initial and Final Values"], {QuantityVariable[ \!\(\*SubscriptBox[\("v"\), \("f"\)]\),"Speed"] -> Quantity[1, ("Meters")/("Seconds")], QuantityVariable[ \!\(\*SubscriptBox[\("v"\), \("i"\)]\),"Speed"] -> Quantity[0, ("Meters")/("Seconds")], QuantityVariable["t","Time"] -> Quantity[1, "Seconds"], QuantityVariable[ \!\(\*SubscriptBox[\("x"\), \("i"\)]\),"Length"] -> Quantity[0, "Meters"]}]
Out[3]=
