Answer:
In a roller coaster, the laws of motion, as described by Newton, are particularly evident. These laws are:
1. **First Law (Law of Inertia)**: An object in motion tends to stay in motion, and an object at rest tends to stay at rest unless acted upon by an external force. This law is evident when the roller coaster is at rest and requires an external force (such as the initial push or lift mechanism) to set it in motion. Once in motion, the roller coaster continues along its path until acted upon by other forces.
2. **Second Law (Law of Acceleration)**: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This law is evident when the roller coaster accelerates or decelerates during various segments of the ride. For example, the coaster accelerates as it descends a hill due to the force of gravity acting on it, and it decelerates as it climbs a hill due to the opposing force.
3. **Third Law (Action-Reaction)**: For every action, there is an equal and opposite reaction. This law is evident in various aspects of the roller coaster ride. For instance, the force exerted by the coaster on the track (action) is met with an equal and opposite force exerted by the track on the coaster (reaction), which allows the coaster to navigate loops, turns, and other elements safely.
These laws govern the motion and dynamics of the roller coaster, ensuring a thrilling yet safe experience for riders.
