Graffiti is a highly controversial and polarizing topic, with some people considering it to be a form of artistic expression and others viewing it as nothing more than vandalism. In this essay, we will examine both sides of the argument to determine whether graffiti should be considered art or vandalism.
On one hand, proponents of graffiti argue that it is a legitimate form of art. They point out that graffiti has a long history dating back to ancient civilizations, where it was often used to convey important messages or tell stories. Graffiti can also be seen as a way for artists to express their creativity and share their ideas with the world. Many graffiti artists take great care in planning and executing their works, using a variety of techniques and styles to create visually striking and thought-provoking pieces.
However, those who view graffiti as vandalism argue that it is a destructive and illegal activity that damages public and private property. Graffiti often appears on buildings, trains, and other public structures without the permission of the property owner, and removing it can be costly and time-consuming. Additionally, some graffiti is used to spread hate speech or gang-related messages, which can create a sense of fear and unrest in a community.
In conclusion, the question of whether graffiti is art or vandalism is highly subjective and depends on one's personal beliefs and values. While some may see it as a legitimate form of artistic expression, others view it as a destructive and illegal activity. Ultimately, it is important to respect the rights of property owners and ensure that graffiti is not used to spread hate or cause harm to others.
What type of lever is a mousetrap car?
The exact type of mechanism needed to transfer the spring energy into forward motion of the car does not matter as long as it enables the spring to release all its energy as the car moves. Therefore, heavier cars will be much less successful than vehicles using much lighter materials due to the amount of friction and inertia, which will not allow the car to travel as far or as fast under the same conditions. The larger the circumference of the wheel is as compared to the radius of the axel, the more mechanical advantage the wheel will have. The goal of the project is to find the most efficient use of the energy provided by the mousetrap for both speed and distance by adjusting the size of the wheel. Momentum is a force that keeps moving objects moving in the same general direction and force until some outside force acts upon the object. PURPOSE The goal of this lab was to build a mousetrap powered car.
Also, more mass involved with the rotation of the axels will cause more friction. This meant finding a larger straw that would fit a dowel rod through it. Pull it as tight as possible, then cut off the excess picture 3. However the larger diameter also requires more energy to make them revolve. Lastly, adjust the length of the arm: add more sticks or cut it shorter until the very end of the arm touches the drive wheel axle.
If the wheels are too small, the axels will have to revolve more times to build up any significant momentum. Click to see full answer Moreover, what simple machine is a mousetrap? The second car we made we had seen a tutorial for a small juice box straw that had a wood skewer running through it. The Frog is the guardian of the stream that divides the unoriginal to the brave and is the sifter to all those who stray from the pack. I also learned that friction and traction were important variables in this experiment. Put the car on the ground and let it go and it should start rolling away from you. RESEARCH …show more content… Therefore, I focused my research on ways to maximize the potential energy.
The various larger sizes were designed to fit over the smallest ones that were attached to the axels. Paw Flapper Lab Report 75 Words 1 Pages First, place the toy in front the dog and then press start on the stopwatch. It should reach a bit longer than hook on the rear axle. Let the mousetrap arm close it points past the front wheels. If the mechanical advantage is too low, then the output force will be too weak to overcome the car's inertia.
You have to determine the ideal drive wheel diameter with trial and error. You have to balance practical considerations with theoretical ones. They only pose a significant hazard when the arm is pulled back and released quickly, so don't be afraid to get in there and start building! A Jumping Mouse discovers the Sacred Mountains by jumping into the reflecting lake and use his new found likeness to go on the adventure that test 's the Jumping Mouse ability to be independent and selfless. This traction helps the wheels to propel the cars across further distances and at greater speeds. Please pin this post for later:. . However, a mousetrap is used instead of an internal combustion engine for the motor.
This is important because the circumference the part that actually touches the track. To determine this, the distance a car travels when tested with the same propulsion force but different wheel diameter is measured. In the end the fastest dog was the Bulldog and the slowest was the Yorkie mixed poodle with poodle. The design of such a car aims at enhancing dynamic performance while maintaining the safety and following the guidelines lay down by the governing body. Mechanical advantage is a phenomenon that increases the efficiency of a simple machine. Attach a piece of string to the end of the ¼ inch dowel with a zip tie. Now if we compared the throwing of the bowling ball down an alley on the earth and then on the moon we would find that there is no apparent difference in force or feel of throwing the bowling ball.
. A two-feet length of nylon string was secured to the copper pipe and the rear axel. Force is measured in newtons, mass is measured in kilograms, and gravity is measured in meters per second per second. Overall in my experiment was testing if different breeds can open the the Paw flapper the toy. Additionally, this equation assumes that the string will be wrapped in a single even layer over the dowel, but there isn't enough space for that; the string will start to wrap around itself, which increases the diameter of the dowel, and therefore results in a fewer number of wraps. I put hollow pens through the eyelet hooks, and the pens served as the axles. The loop should just reach the hook on the rear axle.
Cleaning up small things can have a big impact on performance. Other examples of wheel and axle use include electric fans, motors, revolving doors, and merry-go-rounds, as well as the wheels used on skateboards, roller blades, cars, and many, many more objects. Alternatively, the rod can be cleverly set up so that its center of mass falls by a net amount as it "swings" through its range of motion. If potential energy of the car is released rapidly, the rate of acceleration will be high and car will run faster. Weight does not remain constant and depends on the strength of the gravitational field where the object is being weighed. What simple materials do you need for mouse trap car A? Understanding the principles of these simple machines will help you design your mousetrap vehicle.
Speech On Electric Car 926 Words 4 Pages Topic: Electric car: The Future of Automobile Intro Hook: Electric car is the car that use electrical energy instant of fuel that will replace any car in the future. This is because the mass of the bowling ball is the same in each location and by throwing the bowling ball you are working against it's inertia and not it's weight. There are a couple of approached here. After a few test trials, I concluded that I needed something to keep the axles from moving. The wheels need good traction because without the right amount of friction the wheels attached to the drive axle will slip and not push the car forwards because of all the added torque. Although this will be much less than rolling resistance, every little bit helps. Unspool the string from the roll and cut it so it's about 2-3" past the drive wheel dowel picture 3.
Be sure the dowel is pointing forward away from the notch in the cardboard and that the dowel also lines up with the center of the notch when it is pulled back. For example, the density of the penny from 2005; which was the penny that was experimented on to see whether or not it could turn into silver; was 4. The cars physics are all about mechanical advantage, the trade off between how long it takes to do something and how little force is required to do it. They had to turn in their prototype the next morning for evaluation. Mousetrap powered cars and boats.
