1. Measure the distance from the top of the third floor balcony to the first floor using a tape measurer. It should start from the top railing of the balcony to until it touches the floor. 2. Take a meter stick and place the front of the car at zero. Turn on the car and let it run until the front reaches the end of the meter stick. Make sure to use a timer to see how long it takes the car too travel that far. Divide the change in distance it travel by the time it took to find the velocity of…

Mouse Killing Car Project While building and testing a mousetrap car the builder must understand a few simple but, vital mechanics. The vehicle will be propelled by the pulling force of a small mousetrap. The end goal of building this car is to have it go from one end of the room to the other on top of carpet. Leverage, kinetic energy, and friction; are things to take into consideration while testing and building the car. There are two types of levers to keep in mind. The first is the lever arm…

Swipe bloodstains which is in the catorgory of transfer bloodstain patterns, are created when a wet bloody object comes in contact with a target surface. Its use to identify an object or body part. A wipe pattene is created from an obkect moving through the a bloodstain, while a swipe pattens is created from an obect leaving bloosstain. Number is mark a swipe bloosstain becasue there seems to be a swipe of a hand print or sometime of object that has moved through the bloodstain, their are also…

Paragraph 1: A lever is a simple machine, which is a long rigid object resting on a pivot or a fulcrum, which rotates. This reduces the effort that is needed to move something. In this experiment the lever is the catapults arm. The lever we have used for the throwing arm is classified as a third class lever. The base of the catapult is the fulcrum, where it pivots off. The load is the beanbag on the end of the arm and the effort is how much it takes to pull down the arm of the catapult. Tennis…

There is a common saying that states, “Which weighs more; 200 pounds of bricks or 200 pounds of feathers?” One might say that they both weigh the same; however, the answer is the feathers because you also have to carry the weight of the great injustice done to those poor birds. When I was asked to list all the things I carry, I started listing the physical items, but after a while, I realized that there emotional items that I carry as well. I carry memories and feelings that either haunt or…

Change The cold metal on my bare feet shot a surge of chill through my body. I once again stepped onto that scale, and once again hoped for different results. Glancing down in anticipation as the digital numbers rose, I begged them to stop, and they did; 194, 196, 197, and finally settled upon 198. I did it, I finally dipped below two-hundred pounds for the first time in what felt like forever. At that moment I thought back to the jokes, the comments, and all the looks I received over the past…

These bass can be found in the numerous rivers, lakes and ponds throughout New York. The season for fishing bass in New York is from June to the end…

The seatbelts purpose was to keep the egg secure during the impact. In order to do this, Newton’s first law had to be taken into consideration, objects at rest, stay at rest; object in motion, stay in motion… unless acted upon by an unbalanced force. Because the egg would have kept going until acted on by an unbalanced force, we suspended it with rubber bands so that the unbalanced force to stop it would not be the ground but it would be the pressure applied by the rubber band. This also Apply…

Sullivan Jackson Kachigan Physics 16 February, 2018 SAHC: SJ How Mass Effects Luge Luge is an unusual sport where the rider or riders on a sled-like device are barreling down an ice track at speeds up to 97 mph. Because of these tremendous speeds, one may think that the rider(s) must be light and nimble so they could glide through the course with ease. However, this is the complete opposite of reality and in the physics world, it makes complete sense. As you may have guessed, the…
