They also have a whole list of experiments you can do at home, like turning your phone into a sonar to measure the speed of sound. Or putting it in a salad spinner to study circular motion. Or swinging it on a string to derive the gravitational constant. I decided to try this one, ...
1) Gravity – the constant attraction downwards is an essential grounding force for life on earth. However, gravitational pull acting on a curved spine will further compress the concave or short and tight areas which will reinforces the curvatures. ...
The ability to accurately and reproducibly measure rates of amyloidogenesis is critical for uncovering mechanisms by which pathogenic mutations and post-translational modifications affect protein fibrillization (1, 2, 3) and for discovering compounds that act upon amyloid-like oligomers (4, 5, 6, 7...
We measure the potential difference in volts (which has units of joules per coulomb). The voltage in an electrical circuit controls the current in combination with the resistance. The voltage can be looked at as exerting an electric force on a positive charge (or a negative charge in the opp...
where G is the universal gravitational constant. The analogy between these equations and those in the previous section are evident. Electric Potential Energy Equation The formula of electrostatic potential energy, written U for charged particles, accounts for both the magnitude and polari...
Calculating how long it takes for you to run a mile tells you the average speed over the mile, but not the speed at every given moment during the run. Instead, you can determine a small interval over which to measure speed to get the speed at a single moment during the run, which is...

b) How would the orbital period T of Detail how, if Earth's orbit were twice the diameter it is now, that would affect stellar parallax and our ability to measure distances. Why is the earth's orbital velocity fastest at perihelion? How would you calculate the curvature of the Earth?
