Summary
According to the equation elocity (McGill and King 12), momentum is directly proportional to the velocity of the car. In the results of table in question [1], as the velocity increases the momentum also increases linearly.
7. A fast moving car is likely to cause more…

The ramp will be set up as in the previous lab experiment with the ramp raised 45 cm above the floor. The meter rule will be stacked at the center of the ramp with its zero mark placed at the bottom end of the ramp. An ultrasound reflector will be taped at the back of the model car. The mass of the car is then measured and recorded. A book of about 300g is placed at the 30cm mark from the bottom end of the ramp. The motion detector is fixed at the higher end of the ramp according to the setup in the lab manual. The motion detector is channeled to the computer interface through channel one. The computer is then set for data acquisition. The car is placed at the 80 cm mark on the meter rule. The car is released simultaneously with the sound from the detector. After the car hit the book the distance which the book moves is recorded. Repeat twice and find average of the distance the book moved. The whole procedure is repeated but now with a book of 600g.
To confirm the results for question [9], we repeat the above procedure but now recording average velocity of the car weighing 500g. The procedure is repeated but with a car of mass 1000g. Again the average velocity of the car is recorded. These velocities are used to calculate the momentum of the car at the time of ...Download file to see next pagesRead More

...?Lidia M. Lujan Lab report W14s1 Debate on Global Warming: Scientific Basis Global warming refers to the increase in the temperature of the earth's surface and troposphere. The term global warming is used interchangeably with “climate change,” referring to the other climatic changes aside from or due to increased global temperatures. The change in temperature is attributed directly due to increased in emission of greenhouse gases, largest concentration of which is carbon dioxide. The increased emission arises from human activities in the transport and energy sector (US Environmental Protection Agency). Other human activities like clearing of land, deforestation, and desertification that abet temperature...

...Running head: RECYCLING ALUMINUM TO ALUM Recycling Of Used Aluminum Cans to Alum: A Study Affiliation Introduction Aluminum and its alloys find several applications today, right from soda cans to aircraft material. This is because aluminum is versatile and has many desirable properties: light weight, nontoxic, pleasing appearance, ability to take high polish, high electric and thermal conductivities, corrosion resistance, malleability, ductility, non-magnetic, and non-sparking. (Greenwood & Earnshaw, 1997) Aluminum combines with other metals to give alloys with high mechanical and tensile strengths. The abundance of its ore makes aluminum and its alloys easily available - Aluminum comprises 8.3% by weight of the earth’s crust... head:...

...SUMMARY SHEET Physics Laboratory Report -- Equilibrium of a Rigid Body Objective To be able to determine the center of gravity of a rigid body andpositions of weights with reference to that center that would establish equilibrium of forces and torques Method Obtain the weight (in Newton) of the meter stick and the average weight of the three meter stick clamps. Balance the meter stick in one of the clamps to determine its center of gravity. Place a clamp on one end of the stick to carry a 100-gram weight and slide the stick through the supporting clamp to locate the balance (position of the axis of rotation). Then place another clamp with a 200-g suspension and repeat the same previous step. Record positions with respect...

The niche of an organism is the overall interactions of an organism with other organisms and its range of needs (Properties of microbes). 2. Organisms might compete for food, light, and space. 3. Evolution is the process of gradual development of organisms from simple structures to intricate forms over time. Competition affects the process of evolution in that the organism that is able to compete favorably for the available resources survives and continues to thrive, whereas the organism that cannot compete favorably dies and becomes extinct.

...Lab report Prediction of the Maximum Height Travelled By a Model Rocket The determination of rocket field is useful when in the quest for determining how high a rocket flies, at a given moment. In this lab, the major objective was to predict how high a rocket model could fly once launched. This involved acquiring a model rocket, then launching it to determine the figures for the various variables. Another related objective was to apply equations for basic projectile motion in determining how high a rocket can fly. Since launching the model rocket, this is considered a projectile motion influenced by height of launch pad, gravity and velocity imparted by the engine. Consequently, there...

...Lab Report Introduction This experimental procedure comprises a set of activities that serve to instill and develop students’ technical skills concerning measurement, hand sketching, and creation of CAD drawings. Using a vernier calipers and a micrometer screw gauge as high precision measuring tools, internal and external measurements of a Duplo block were to be determined. Additionally, measurement features and precision aspects of these instruments were reviewed for familiarity. Sketching and outlining drawings of this Duplo block entails a combined application of techniques in engineering that aid in manufacture of objects, with Duplo block as a sample (Benedettelli, 2014). Like any other laboratory...

...while in the case of measurement 2; it is 1.59m/s. 3 This lab experiment is relevant to many scenarios in life. When an object travels in the circular motion, its speed is constant which implies that the magnitude of the objects velocity is not changing while the direction changes. On a practical sense, the activity of driving around a curvy road is equivalent to this lab experiment. For a constant speed, tighter curves tend to generate a greater centripetal acceleration provided by the friction between the tires and the road. This can be described as follows: for steady speed, the equation of centripetal force has it that acceleration is indirectly proportional to the radii of the curve. When a car...

.... A normal pendulum with a few modifications can be used to achieve similar objectives. In this case, a zero position for the pendulum is identified. Since many labs are done on tabletops, the table top is assigned to be the zero height (mean) position. If the tabletop is designated the zero position, then the PE of an object is dependent on its relative height from the tabletop. Therefore, by obtaining the mass of the pendulum and its relative height from the table top, the gravitational potential energy can be calculated follow: PE = mass x relative height x Gravitational pull = mgh 2. As a car goes over a rough road or bumps, the spring in its shock-absorber setup is compressed, but the...
