Answer
Nina kept moving forward because of inertia, which made her body resist stopping while the skateboard was stopped by the rough pavement.
Solution
Nina kept moving forward due to the principle of inertia, which is a concept from Newton's First Law of Motion. This law states that an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.
In this scenario:
1. **Initial Motion**: Nina was riding the skateboard, which was in motion.
2. **Rough Patch**: When the skateboard hit the rough patch of pavement, it experienced a significant increase in friction, which acted as an external force that stopped the skateboard.
3. **Inertia**: However, Nina's body, which was in motion, continued to move forward because there was no immediate force acting on her to stop her motion. This is due to inertia, which is the tendency of an object to resist changes in its state of motion.
Thus, while the skateboard stopped, Nina's inertia caused her to continue moving forward until she eventually fell or was stopped by another force (like the ground).

inertia, which is the tendency of an object to resist changes in its state of motion. In simpler terms, when you're moving and suddenly hit an obstacle, your body wants to keep moving at the same speed. This is why skateboarders wear protective gear—crashes can result in unexpected flips and hard landings! To help prevent mishaps like Nina's, it's crucial to practice awareness of your surroundings. Always scan the path before you and be ready to react to unexpected changes. A common mistake is underestimating rough surfaces, so take the time to navigate around obstacles or gradually approach them to maintain balance and control. Remember, safety first!
