You pull your hands back while catching a fast moving cricket ball. Which law is used to explain it?

• A. law of inertia
• B. Newton’s second law of motion
• C. Newton’s first law of motion
• D. Newton’s third law of motion

When you pull your hands back while catching a fast-moving cricket ball, you are demonstrating the concept of inertia, which is explained by Newton's first law of motion. This law states that an object in motion will stay in motion unless acted upon by an external force. By moving your hands back, you reduce the impact force on your hands, allowing for a safer catch.

Key Concepts

• Inertia: The tendency of an object to resist changes in its state of motion.
• Newton's First Law: Also known as the law of inertia, it highlights how objects behave when forces are applied.

Why This Matters

Understanding this principle helps in sports and everyday situations where catching or stopping moving objects is involved. It emphasizes the importance of technique in preventing injury and improving performance.
