I need a website that will show an object in motion then calculate the speed, acceleration and momentum

There are various physics simulation tools available online that can help you visualize object motion and calculate speed, acceleration, and momentum. One such website is "PhET Interactive Simulations" by the University of Colorado Boulder. They provide a collection of interactive simulations, including ones specifically focused on motion.

Here's how you can use it to fulfill your requirements:

1. Visit the PhET Interactive Simulations website (https://phet.colorado.edu/).
2. In the search bar at the top-right corner, type "motion" or a related keyword to find relevant simulations.
3. Choose a simulation that suits your needs, such as "The Moving Man" or "Motion in 2D".
4. Open the simulation, and you'll be presented with a graphical environment where you can manipulate objects and observe their motion.
5. Use the available controls to set up the initial conditions, start the motion, and adjust any relevant parameters.
6. As the object moves, the simulation will display its speed, acceleration, and momentum in real-time. You can also pause the simulation at any moment to analyze the values more accurately.

Remember that these simulations are intended to provide visual aids for learning and understanding physics concepts. The values obtained from these simulations might not be precise enough for scientific research, as they simplify real-world scenarios.

Additionally, various educational websites and physics textbooks offer calculators or step-by-step explanations for specific motion scenarios. You can search for those resources if you need precise calculations for custom scenarios.
