Description

The provided code generates synthetic data to simulate the dynamics of fear under the influence of external and decision-making forces. Let's delve into the components and describe the characteristics of the generated data: System Components: Mass of Fear Element: mass: A constant representing the mass of the fear element. In physics, mass influences how an object responds to external forces. Time Array: Time: An array representing time, ranging from 0 to 10 with steps of 0.1. This defines the temporal aspect of the simulation. Forces: external_force: Simulated external force, represented by the sine function over time. It models environmental factors impacting fear. decision_force: Simulated decision-making force, a linear function of time. It represents an illustrative force related to decision-making. Fear Dynamics Simulation: The fear dynamics are simulated using numerical integration. The fear element's position (fear_position) and velocity (fear_velocity) are updated over time based on the external and decision-making forces. Visualisation: The simulated fear dynamics are visualised through two subplots: Forces Influencing Fear Dynamics: External force and decision force are plotted against time. This provides insight into how these forces vary over the simulation duration. Fear Dynamics with Decision-Making: Fear element position is plotted against time. This plot illustrates how the fear element's position evolves over time, considering both external and decision-making forces. Key Takeaways: The simulation combines external and decision-making forces to model fear dynamics. Visualisation helps understand the impact of forces on fear over time. This is a simplified model, and specific force functions can be adjusted for more realistic simulations. Note: In a real-world scenario, such simulations can be more complex, considering various factors and interactions influencing fear dynamics. This model provides a foundational understanding for more intricate simulations.
