They will "affect" the impact of the object with the ground:

Explanation:

When you drop an object it will fall under the influence of gravity and reach the ground;
at the instant before the impact it will have a certain momentum ${\to p}_{1} = m {\to v}_{1}$ $vecp_1=mvecv_1$ (a vector, with modulus AND direction). On impact your object will receive an impulse from the normal force $N (t)$ $N(t)$ (not constant but variable according to the time of contact).

After the impact the momentum ${\to p}_{2} = m {\to v}_{2}$ $vecp_2=mvecv_2$ will be "reversed" compared to the initial one (before impact).
The process you observe could be described, visually, as:
