Buoyancy & Interactive Physics Simulations Study Guide

I. Key Concepts & Topics

• Buoyancy Force: The upward force exerted by a fluid that opposes the weight of an immersed object.
• Mass: A measure of the amount of matter in an object.
• Weight: The force exerted on an object due to gravity.
• Density: Mass per unit volume. A crucial factor determining whether an object will float or sink.
• JavaScript Simulation Applet: An interactive computer program, written in JavaScript, designed to simulate physical phenomena.
• Open Educational Resources (OER): Freely accessible and openly licensed educational materials.
• HTML5: The latest evolution of the standard that defines HTML.
• Sliders: A GUI element that allows users to adjust values within a defined range.
• Drag-able Objects: GUI objects that the user can click on and drag to another location on the interface.

II. Quiz (Short Answer)

1. What is buoyancy force, and in which direction does it act?
2. How does the density of an object compare to the density of the fluid it is in, to determine if it floats or sinks?

III. Quiz Answer Key

1. Buoyancy force is the upward force exerted by a fluid on an object immersed in it. It acts in the opposite direction of gravity, upwards.
2. If an object's density is less than the fluid's density, it floats. If the object's density is greater, it sinks. If they are equal, the object is neutrally buoyant.
3. It allows users to interactively explore the relationship between mass, weight, density, and buoyancy force through a visual simulation.
4. Two adjustable parameters include the height of the object and its vertical position via dragging.
5. OER stands for Open Educational Resources. They are important because they provide free and accessible learning materials to anyone, promoting educational equity.
6. It means it can be run in a web browser without requiring additional plugins and is compatible with various devices.
7. The user can adjust the vertical position by dragging the center of the hanging scale vertically.
8. The Reset button returns all the simulation's parameters to their initial default values.
9. One example of another javascript applet is Multiple Objects ( solid ball , football disc, car ) Rolling Down Inclined Plane JavaScript Simulation Applet HTML5 with Export Function for Analysis on SpreadSheets.
10. One of the awards Open Source Physics @ Singapore has won is UNESCO King Hamad Bin Isa Al-Khalifa Prize for the Use of ICTs in Education 2015-6.
