First of all, the natural "justification" is that animals themselves eat meat. Whether you are religious and believe that God (or whatever else you worship) ordained certain animals to be eaten or if you are a believer in unaided evolution, where early humans began to work together hunting and...
Our semester project in ap physics was shooting a projectile with a projectile gun at an angle at a cm^3 box traveling up (or down) an inclined plane.
Our teacher chose the angle of our gun, the angle of the incline, the mass in the box and countermass (attached to a pully at the top of the...
you guys were probably right about te bad measurement of the angle.
i did take into account the fact that they were on different levels, and the air resistance was generally negligible
yes the gun was producing precise shots, we used carbon paper to see where they were landings and they were mostly overlapping.
we were inside so there wasnt much worry about wind. we measured the angle to the best of our ability, and we were right on horizontally just not vertically.
mass isn't the only unit of measure we have trouble defining
temperature: "the average kinetic energy of an object"
Say an object is sitting still on a table. it would have a kinetic energy of 0, except for the fact that the Earth is spining. If the Earth wasn't spinning then it would have...
Today, our AP physics class had a lab.
The task was to caclulate the velocity of a projectile gun, then the next day place the gun at an angle, which we measure and calculate the distance away to place a street cone with a hole cut through the top so that the projectile would land directly in...
