Question

1. collisions change the ______________ of objects. a. direction b. speed c. both a and b d. neither a nor b

Explanation:

In physics, collisions can cause a change in an object's direction and/or speed. For example, in an elastic collision, both speed and direction might change depending on the masses and initial velocities of the colliding objects. In an in - elastic collision, the objects might stick together and their combined speed and direction will be different from the initial ones of the individual objects.

Answer:

C. both A and B
