How does the PhET simulation work?
PhET provides fun, free, interactive, research-based science and mathematics simulations. These tests include student interviews and observation of simulation use in classrooms. The simulations are written in Java, Flash or HTML5, and can be run online or downloaded to your computer.
How do I download PhET simulation?
Download the PhET CD-ROM Distribution archive onto your computer (280 MB). Extract the contents of the archive (on most operating systems, this is done by double-clicking the downloaded file). Copy all the files to the CD-ROM. Please remember to periodically check for updated versions of the PhET simulations.
Do PhET simulations work on Chromebooks?
Individual Chromebook The PhET Simulations Android app is compatible with select Chromebooks and allows native offline use of all the HTML5 sims and can be downloaded on Google Play.
How many PhET simulations are there?
The project now designs, develops, and releases over 125 free interactive simulations for educational use in the fields of physics, chemistry, biology, earth science, and mathematics.
What are balanced forces examples?
Examples of balanced forces:
- The weight of an object and the normal force acting on a body are balanced.
- A car that is pushed from opposite sides with equal force.
- A lizard on a wall in a vertical position.
- A ball hanging by a rope.
- A weighing balance where the weight in both of the pans is exactly equal.
What are the forces of motion?
Forces influence objects that are at rest or that are already in motion. Isaac Newton’s three laws of motion involve inertia, mass, velocity, and momentum. Key forces include gravity, friction, and magnetism.
What is molecular shape in chemistry?
Molecular Shape The Shape of Molecules. The three dimensional shape or configuration of a molecule is an important characteristic. Isomers. It is necessary to draw structural formulas for organic compounds because in most cases a molecular formula does not uniquely represent a single compound. Resonance. Atomic and Molecular Orbitals.
What are molecular shapes?
Molecular shape is the three dimensional arrangement of atoms in space around a central atom. The molecular formula of a substance does not give an indication of its shape.
What is polarity in chemistry?
1 Answer. Answer: In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multi-pole moment.
What is the definition of polar chemistry?
In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end.
