Motion - practice problems
Word motion problems can be divided into three basic groups:1. bodies come from one place.
2. the bodies go against each other.
3. bodies move in space, e.g., after the ballistic curve, falling, etc.
The basic formula is s = v * t, i.e., the path is equal to the speed multiplied by the movement time.
