Physics Simulator Plus
Read full descriptionHide full description
Physics Simulation is an easy-to-use tool for creating physics-animated illustrations. It allows anyone with a good understanding of math or physics to create animations and simulations effortlessly. It features a user-friendly control panel, making it perfect for casual users. Features: ∙ Easily create Free Fall or Collision simulations. ∙ Create, preview, and learn physics and math interactively. Project Management: ∙ Create and save physics simulations as projects. ∙ Edit or delete projects. ∙ Projects are transferable to other devices using the Files app. Simply go to Physics Simulator and copy the Project folder. Project Settings: ∙ Enable/disable Gravity (9.8 m/s²). ∙ Enable/disable Border Walls. ∙ Enable/disable Grid. ∙ Enable/disable Motion Arrows (for a better understanding of object motion direction). ∙ Enable/disable Mass Labels (for a quick review of object mass). ∙ Adjust Playback Speed (ranging from 0.1x to 3.0x for slow or fast simulation playback). Object Settings: ∙ In Edit Mode, touch and drag to reposition an object or double-tap to edit its properties. ∙ Add Balls or Rectangles. ∙ Edit or delete objects. ∙ Adjust Ball Size (10-100). ∙ Adjust Rectangle Size (10-100). ∙ Assign custom colors to objects. ∙ Set objects as Static or Dynamic. ∙ Adjust Object Mass (0-100 kg). Object Physics Properties: Is Dynamic – Indicates whether the object moves due to physics simulation. If false, the object remains static. Mass – Defines the object's weight in kilograms. Mass affects momentum and how forces interact with the object. Friction – Determines surface roughness and applies frictional force when objects collide (range: 0.0 - 1.0, default: 0.2). Restitution – Controls bounciness; determines how much energy is lost when an object bounces (range: 0.0 - 1.0, default: 0.2). Linear Damping – Reduces the object's linear velocity, simulating air or fluid resistance (range: 0.0 - 1.0, default: 0.1; 0.0 means no damping). Angular Damping – Reduces rotational velocity to simulate air or fluid friction (range: 0.0 - 1.0, default: 0.1; 0.0 means no damping). Velocity – The object's movement speed, measured in meters per second. Angular Velocity – The object's rotational speed, measured in radians per second. Quick Start Guide: 1. Tap the New File icon to start (this clears all objects). 2. Tap the Settings button. 3. Ensure Gravity and Walls are enabled, then tap Back. 4. Tap the Circle button, then tap the center of the screen to add a ball. 5. Tap the Edit button. 6. Double-tap the ball to open the Object Properties page. 7. Adjust the Size to 50. 8. Tap Back to see the updated ball size. 9. Tap the Play button to run the simulation. Tips: ∙ Use the Grid Overlay to align objects precisely. ∙ In Edit Mode, drag to reposition objects or double-tap to modify their properties. * Check out the Library for example projects. About Physics Simulation A physics simulation starts with a mathematical model where variables define the system's state at a given time. Each variable represents an object's position or velocity. The core of a physics simulation is a set of differential equations that determine how these variables evolve over time.

Verdict
The clearest difference is price: Spirit Board at Free against Physics Simulator Plus's $3.99. Spirit Board also leads on update cadence (every 2 months vs every 25 months). Physics Simulator Plus's advantage is in-app purchases (none vs 2) and device support (3 vs 1). On ads there is nothing between them.
