The simulation shows a ballistics cart. If the cart is at rest on a horizontal surface, it will shoot a ball straight up in the air, and catch the ball again. What if, as in this simulation, the cart is traveling at a constant velocity horizontally, instead? Will the ball land ahead of the cart, in the cart, or behind the cart? Note that the cart fires the ball straight up, with respect to the cart, when the middle of the cart passes the small vertical trigger on the track.
Use the buttons to select the different modes (whether there is a tunnel or not, and whether to show the velocity vectors).

This simulation shows the difference between Constant Velocity vs. Constant Acceleration هذه المحاكاة تبين الفرق بين السرعه الثابته والتسارع المستمر في الفيزياء

The simulation shows five different motions in which objects experience constant acceleration, starting from rest. Although each motion is different, the underlying physics is the same. What features of the simulation reinforce the idea that the physics is the same?

This web page features a collection of Easy Java Simulations developed by secondary teachers for use in introductory high school physics courses. Topics include astronomy, momentum and collision, projectile motion, Gauss's Law and electric field, special relativity, and more. Each simulation is accompanied by a standards-based lesson plan and printable student guides. Users may run the simulations as a Java applet or may directly download a jar file version. The materials in this collection were created with Easy Java Simulations (EJS), a modeling tool that allows users without formal programming experience to generate computer models and simulations. To modify or customize the model, See Related Materials for detailed instructions on installing and running the EJS Modeling and Authoring Tool. This resource is part of Project ITOP (Improving the Teaching of Physics), a graduate program offered at University of Massachusetts-Boston. The archived computer models are hosted and maintained as part of the BU Physics Simulation collection.

The simulation illustrates the situation of a person in an elevator. The elevator takes the person from one floor to the next floor up.
For this situation, try sketching three free-body diagrams, one for the person, another for the elevator, and a third for the person-elevator system.
First, draw the diagrams for when the system remains at rest. Then, predict whether the free-body diagrams will change (and, if so, how) when the elevator is accelerating up, moving up at constant velocity, and moving up but slowing down (acceleration is down).

The simulation draws the diagrams for all these cases, but make sure you try drawing your own before looking at the simulation's diagrams.

The simulation beeps each time the ball passes one of the vertical red lines. Just like the bells on Galileo's ramp, the positions of three of the vertical red lines can be adjusted. The first line and the last line are fixed in place, but the sliders allow you to adjust the positions of the second, third, and fourth lines. Move the lines around until the beeps occur at regular time intervals (make sure the sound is on, on your computer or mobile device).

This is a simulation of the trade which took place between Africa and Asia between approximately 1000 and 1500 on the Indian Ocean. It demonstrates that Africa played a crucial role in the world economy long before contact with European nations. It allows students to use basic principles of economics as they conduct “trade” between the two continents.

In this lesson, students will define and give examples of organic molecules and become aware of the structure and function of the four classes of organic molecules. They will also use simple chemical tests to determine the presence of various organic molecules in everyday foods.

In this unit, students use newspaper articles as models to write their own narratives as reporters. Students construct understandings about journalism and the job of a newspaper reporter through guided inquiry. They review how to read, analyze, and critique models of narrative writing in news articles. Then, students will learn how to conduct interviews and quote dialogue from the interviews as evidence to support the main ideas in their articles, using what they’ve learned about writing for a newspaper from exemplary models.

This simulation involves relative velocity in one dimension. It is an out-and-back race between two women. Mia runs on the moving sidewalk, while Brandi runs on the non-moving floor. Under what conditions is the race a tie? Under what conditions does Mia win? Under what conditions does Brandi win?

This lesson provides an introduction for students to understand the economic and arbitrary motivations of the European powers in the colonization of Africa. Students will participate in an activity that simulates the scramble for colony claims, with the goal to procure as many resources as they possibly can for their assigned European power.

In this simulation, you see, on the left, a picture of a box at rest on a table. You can apply a force to the box - note that you set the y-component and the x-component separately. On the right, you can see the full free-body diagram of the box. The free-body diagram shows the gravitational force exerted on the box by the Earth, the normal force exerted by the table, the force that you apply, and, if there is one, the static force of friction. Note that, on the free-body diagram, the force of gravity and the normal force have been shifted horizontally a little so they can be seen more easily. If there is a net force, that is also indicated.
