What is the term for when two objects hit each other?

• A. Impact
• B. Collision
• C. Interaction
• D. Absorption

Answer: (B)

The term that accurately describes the event when two objects hit each other is "collision." In physics, a collision refers specifically to an event where two bodies exert forces on each other for a short period due to their interaction. During a collision, the momentum and kinetic energy (depending on the type of collision) of the objects can be transferred or transformed, leading to various outcomes such as elastic or inelastic collisions. The term "impact" is often used interchangeably with collision in everyday language, but in a more specific physics context, it can refer to the force that is generated at the moment of collision rather than the event itself. "Interaction" is a broader term that encompasses all types of forces acting between objects, not limited to just the context of colliding. "Absorption" typically refers to the process in which one object takes up energy from another (like a sponge with water) but does not specifically denote the act of two objects colliding. Therefore, "collision" is the most precise term in describing the event of two objects hitting each other.
