Part D: Short Answer Questions (5 marks)

1. Newton's First Law of Motion states that an object will remain at rest or continue moving at a constant velocity unless acted upon by an external force.
2. Erosion is the process of wearing away or moving soil, rocks, or other materials by natural forces such as water, wind, or ice. Example: The Grand Canyon formed due to erosion by the Colorado River.
3. The purpose of a control group in an experiment is to provide a baseline for comparison. It is used to establish the effects of variables by comparing results with a group that is not subjected to the experimental treatment.
4. Two major components of the nervous system are the brain and spinal cord.
5. A physical change only alters the physical properties of a substance, such as size, shape, or phase (solid, liquid, gas). A chemical change, on the other hand, involves a chemical reaction that results in the formation of new substances with different properties.
