Momentum

The science behind something you encounter, use, or wonder about.

  1. The useful idea

    In Newtonian mechanics, momentum (pl.: momenta or momentums; more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object.

  2. How it works

    It is a vector quantity, possessing a magnitude and a direction.

  3. Why it matters

    If m is an object's mass and v is its velocity (also a vector quantity), then the object's momentum p (from Latin pellere "push, drive") is: p = m v . {\displaystyle \mathbf {p} =m\mathbf {v} .} In the

Look for Momentum the next time you notice this pattern in everyday life.
