Forces and motion simulator
Force experiments are most useful when one variable changes at a time. Build a free-body picture of the scene, predict the acceleration, and compare the prediction with the simulation.
Open the interactive physics simulatorConcepts to investigate
- Resultant force
- Friction
- Weight and normal reaction
- Elastic force
How to use the simulator
- Choose a prepared experiment or create a scene with approved objects.
- Predict what will happen before changing a single variable.
- Run, pause, reset, inspect, and graph supported measurements.
- Compare the result with the model limitations and an independent calculation or practical measurement.
