Common questions

What is the Momentum formula?

Momentum is written p = mv. Momentum is mass times velocity, a conserved quantity. It belongs to Mechanics, under Momentum.

What are the units in p = mv?

In SI units, p is momentum, measured in kg·m/s; m is mass, measured in kg; v is velocity, measured in m/s.

How is the Momentum formula derived?

Defined as p = mv. Newton wrote F = dp/dt. The result is p = mv.
