Question

what happens when one object has low mass, low speed? low mass, high speed?

Explanation:

The momentum of an object is given by $p = mv$ (where $p$ is momentum, $m$ is mass and $v$ is speed). When an object has low mass and low speed, its momentum is low as momentum is directly proportional to both mass and speed. When it has low mass but high speed, its momentum can still be significant depending on the values of mass and speed, as the high - speed factor can compensate for the low mass to some extent. In terms of kinetic energy $K=\frac{1}{2}mv^{2}$, low mass and low speed result in low kinetic energy, while low mass and high speed can result in relatively higher kinetic energy.

Answer:

When an object has low mass and low speed, it has low momentum and low kinetic energy. When it has low mass and high speed, it can have significant momentum and relatively higher kinetic energy.
