The simplest questions are often the best. Robert P Crease tries to answer one from a physics student in Kenya Seeking perfection Tennis balls are a low-cost way to explore simple physics concepts, ...

Materials Needed: a piece of flannel which is clean and dry or paper towel, stream of water, flexible plastic ruler and a party balloon. In order for the stream of water to flow out, you need to open ...

Everyone needs some “go to” demos. Personally, I like this one. It’s not too difficult to build and it’s easy to use. Take a large block of wood (it needs to have a good mass). I used a left over ...

Materials Needed: A can of root beer, a can of diet root beer, a large container of water and a deep sink or a bathtub. This experiment number four on our list of simple physics experiments with ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...

Through CU Boulder’s Physics through Evidence, Empowerment through Reasoning (PEER) Physics project, Professor Valerie Otero and her team are working with teachers to provide resources to support ...

The United States should fund proposed projects to dramatically scale up its efforts in five areas of high-energy physics, an influential panel of scientists has concluded. Topping the ranking is the ...
