Final answer:
Altering risk by making adjustments to position and/or speed is a concept in Physics that involves understanding the effects of position and speed adjustments on risk levels.
Step-by-step explanation:
The subject discussed in this question is Physics.
When it comes to altering risk by making adjustments to position and/or speed, there are various examples that can be considered. One example is a person standing up from a seated position, as this change in position affects the person's center of mass and stability. Another example is a car accelerating while driving, as the increase in speed affects the car's momentum and ability to maneuver.
Overall, both position and speed adjustments can have an impact on the level of risk involved in various situations, and understanding their effects is important in the field of Physics.
