I have to create a teaching aid for physics based on the principles i have learnt like gravitation , mechanical properties and many more. I am not able to find the right experiment to demonstrate infront of my teacher.Please help me deal with this by providing information about the related matter

If anyone has any topic or knows any website link for creating the teaching aid please post it here

Rearrange the equation ao that A appears on the left hand side of the equation on its own. B=3A+2C+8

I am really confused, i understand that we you do to one side of the equation you do to the other. But how do you know what to add or subtract, is it the 8 or the 2C or...

thanks in advance

You should have posted your question separately, not as an answer to someone else. Use the command

"Post a new Question" at the top of a Jiskha page.

First switch sides (since they want A on the left), and then subtract 2C + 8 from both sides.

3A = B - 2C -8

Next, divide both sides by 3.

A = B/3 -2C/3 - 8/3

When it comes to creating a teaching aid for physics, there are several ways you can effectively demonstrate concepts such as gravitation and mechanical properties. Here are a few ideas that you can consider:

1. Pendulum Experiment: Set up a simple pendulum using a string and a weight (such as a ball or a bob). By varying the length of the string, you can demonstrate how the period of oscillation changes with different lengths. This experiment can help illustrate the relationship between gravity, mass, and motion.

2. Simple Machines: Create a working model or a diagram displaying various simple machines like pulleys, levers, inclined planes, or gears. Show how these machines can be used to amplify force, reduce force, or change the direction of force. This can help students understand mechanical advantage and the principles behind them.

3. Buoyancy: Fill a tank or a large container with water and demonstrate how different objects float or sink. Use different materials with varying densities and shapes to explain the concept of buoyancy, Archimedes' principle, and the effects of gravitational forces on objects in fluids.

4. Elasticity: Explore the concept of elasticity by demonstrating how different elastic materials respond to applied forces. For example, you can use springs of different materials or thicknesses and show how they stretch or compress under different loads. This can help explain Hooke's Law and the relationship between force and displacement.

As for finding more detailed instructions or additional ideas, there are several websites and resources you can refer to:

1. PhET Interactive Simulations (https://phet.colorado.edu): This website provides a wide range of interactive simulations and virtual experiments that cover various physics topics. You can find simulations related to mechanics, gravity, and more.

2. Exploratorium (https://www.exploratorium.edu): The Exploratorium is an interactive science museum that provides online resources, including videos, articles, and activity guides. They have a dedicated section for physics experiments and demonstrations.

3. American Association of Physics Teachers (https://www.aapt.org): The AAPT website has a collection of resources, including lesson plans, activities, and publications. You can find ideas for hands-on experiments and demonstrations suitable for different physics topics.

Remember, when creating a teaching aid, it's important to consider your target audience, the available materials, and the safety precautions necessary for each experiment.
