If you drop a heavy object and a light object simultaneously, which one will reach the ground first? A lot of people will say the heavy object, but what about those who know both will land at the same time? What do they think? Some believe both objects have the same gravitational pull on them and/or both fall to the ground with the same constant speed. Neither of these things is true, however. The force is greater on the heavy object and both objects accelerate at the same rate as they…


via Rainbow Rowell ... As the chandelier falls, EVERYONE dives out of the way. Harry, Draco, everyone. EXCEPT Ron. Ron dives TOWARDS it in order to grab Hermione and get her to safety. I just. Why do people ship anything but Romione again? He is the ONLY one that stayed upright AND moved towards the potentially deadly falling object to save the woman he loves. That is all.


All about Acceleration due to gravity (g) Acceleration due to gravity Acceleration due to gravity (g) is known when a free falling object from a certain is attains a final velocity. Then take g=9.81m/s/s because this will give you a more accurate answer.There are slight variations in this numerical value (to the second decimal place) that are dependent primarily upon on altitude that is why g = 9.8m/s/s sometimes. Take it as 9.8 or 10m/s/s if you are given in the question. How do I…


Egg in a Bottle

Fifth Grade Physical Science Activities: The Incredible Flexible Egg Experiment. In this experiment, a hard-boiled egg will fit through an impossibly small opening with the help of only a few matches. Your child will be amazed, and you'll be teaching her how seemly impossible acts are anything but—with the help of a little science!
