What is Force in Physics?
In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull.
Real-life examples of forces include pushing a door open, pulling a cart, kneading dough (which changes its shape), or stretching a rubber band.
Types of Forces You Can Simulate
- Gravity: The force that pulls objects toward each other. In our simulator, you can adjust vertical gravity to simulate different planets or zero-gravity environments.
- Wind (Horizontal Force): A constant horizontal force applied to all objects, mimicking strong wind currents pushing objects across the screen.
- Friction: The resistance that one surface or object encounters when moving over another. High friction brings objects to a stop faster.
- Restitution (Bounciness): This determines how much kinetic energy is retained after a collision. A restitution of 1.0 means perfectly elastic (super bouncy), while 0 means no bounce at all.
Frequently Asked Questions
Can I export the simulation?
Yes! Use the "Export PNG Snapshot" button to download a high-resolution image of your current simulation state.
Is this tool free?
Yes, our Interactive Force Simulator is completely free to use online with no hidden fees or sign-ups.
How do I apply manual force?
You can click and drag any spawned object on the canvas using your mouse or touch screen. This applies a direct spring-like force vector to the object, pulling it towards your cursor.
