I agree, less torque with reduced surface area means less tension being applied to the pencil ! If you place said pencil in a fixed place, such as two eye hole screws. Put the pencil into these holes, which are spaced about a inch apart and you use your fingers to break the pencil. The applied...

Mentor note: this discussion was split out of a different thread. The speed of light in a vacuum is constant, but what I would like some information regarding is Black Holes. Does a Black Hole increase the speed of a light photon as it is being pulled into the Event Horizon?

Your question has a lot of variables, such as surface friction, regular tires/ studded, vehicle weight, percent grade of roadway and driver reaction. For each variable, you would use a different equation, resulting in a different stopping distance . Are you allowing for these variables in your...

Hello, I recently read that Japanese scientist are researching ways to store wind energy. Building these turbines with battery's used for storing wind energy included in the design. Making these turbines bigger, propose a problem. They overheat, sometimes catch fire, as we all seen in that...

I was just wondering, if ball A has the same mass as B, but A being larger than B, would A not cover more surface area than B, so there for would have more volume coming in contact with water, creating a greater force on A, If you have two balls, one having A larger surface area, if you try...
