A cyclist can easily balance a bicycle while in motion primarily due to the conservation of angular momentum. As the wheels spin, they generate angular momentum, which provides stability and helps maintain balance.
Evaluation of Options:
Due to the friction of the road
- Incorrect: While road friction is essential for movement and control, it doesn't directly contribute to balance.
Due to conservation of angular momentum
- Correct: The spinning wheels create angular momentum, aiding in balance.
Due to conservation of energy
- Incorrect: Conservation of energy pertains to the total energy in a system but doesn't directly influence balance.
Due to Earth's gravitational pull
- Incorrect: Gravity acts downward and doesn't assist in balancing a moving bicycle.
Answer: (2) Due to conservation of angular momentum
