The Conservation Of Energy Lab Essay

1. When we say that something gives us “energy,” what does that mean? What is a biological definition of energy?

The track begins with a steep climp, building up potential energy in the coaster car. The rest of the

The track and the gravitational force provides a centripetal force that is needed to keep the roller coaster moving in a circular motion, therefore keeping people safe. To continuously change the direction of the vehicle on a curved path, the centripetal force is pushing towards the center of the circle keeping the roller coaster on the

To investigate the gravitational potential energy, kinetic energy, and mechanical energy of the cart as it goes down the ramp.

However, a loop for a roller coaster is not a circle, called a vertical loop, rather it is a teardrop shape. It has been discovered over the years that having a more circular loop can cause severe neck and head injuries because of the intense force from the radius of the loop. Loops are nowadays formed into a clothoid loop to ensure safety and reduce pressure. While going up the loop, the car is acting against gravity, making it move slower as it gets to the top of the loop. Once the car has passed the middle it begins to move faster with the help of gravity. If the loop curvature is constant than it will emit the greatest force at the end of the loop. If the curvature of the loop is not a constant track then riders will feel the “jerks”

Another variable for energy loss is friction, which creates heat, slowing down the cart due to drag force. The wheels between the tracks cause the friction and as the car moves through the roller coaster and takes corners the normal force increases making the force of friction increase, which in turn the loss of friction increases. Sound is another factor for energy loss, the energy is produced when the friction is the highest and it was observed that in the first loop the sound increased as the car approached the highest point in the loop. The same can be observed with the second loop and with the inverted curve as the car reached the entrance. Parallax affects energy loss within the roller coaster due to the wrong calculations. When viewing the videos, it was difficult to determine where the cart reached each location.

Energy is a very important property, it can only be conserved. Energy can’t be created or destroyed, but it can be transferred between objects. Kinetic energy is in the form of motion, sound waves, and or heat. For example, kinetic energy could be the heat from the use of the phone during the day or as the phone falls to the floor. Where as potential energy is the energy that is stored for later use. An example of potential energy would be chemical energy in the battery of your phone or light from the screen of your phone. In addition, law of conservation of energy is energy that is not created or destroyed but just changes form. An example of this would be when you drive your car; you convert chemical energy into mostly mechanical and thermal energy.

In the experiment we had to launch two items and in the experiment we used energy. Mostly kinetic energy but still potenital. When launching the object on the catapult we used kintic energy. When pulling the arm of the catapult we used elastic potential energy becuase

When the new Southeast Polk High School opened they added many new energy saving products. This included installing geothermal heating under the high school cutting back on the cost of heating such a large building. Many new windows help save on energy used to light the building along with automatic lights that turn off after several minutes without movement. The new high school shows how easy it is to save money and help the environment. Renewable energy is good for all aspects of the U.S, providing jobs, economical growth, environmental cleanliness, and new research for improving energy efficiency. Therefore the United States should use renewable energy to benefit the economy and environment.

The purpose of this experiment was to replicate Galileo’s incline experiment and to see if the classroom experiment would produce the exact measurement for the acceleration of gravity in meters per seconds squared that Galileo produced. It was hypothesized that the solid metal ball would have an acceleration of gravity between 9.8 and 10 meters per second squared.

A cart of mass (m) is released from rest on a frictionless ramp. Apply your previous knowledge about energy and motion on frictionless tracks to determine what will happen if the initial height (h) of the cart is larger than the diameter of the loop-the-loop. Choose all that apply. (Apply)

There are many forms of energy. The types of energy that can affect the toy car are potential energy, kinetic energy, and work of friction. Potential is the energy of an object due to its position. Kinetic energy is the energy due to motion. Friction plays a part because it shows how much energy is needed for the car to move. All these energies are intertwined in the toy car.

In the world of force, when Physicists are talking about apply forces, the relationship between mass and acceleration has been attractive for long. Although Sir Isaac Newton has already solved this problem centuries ago, it is still crucial to perform an experiment to prove this relationship to enhance one’s understanding in force. In order to pursue accuracy and objection in the lab, one assumes that he has no knowledge about Newton’s Second Law.

How is energy produced from the resource? Nuclear energy is the power produced during a nuclear reaction. It can produce in two different ways like, nuclear fission and nuclear fusion. It is from the sun and stars which releases heat and light energy to warm up the earth. How much nuclear energy do we use? It has been said that it produces 13-14% of the world’s electricity and it accounts for 6% of the world’s energy, France and japan make up 50% alone, and the U.S. has been producing 20% since 1991. What are the prospects for this resource in the future? They say that from now until 2040 that it will go up by 14% and that the generators will be updated and new fuel cycles. What are the pros and cons for each resource? Coal: Pros- its

The first law of thermodynamics defines that energy can be transformed but not destroyed. It's used to define the internal energy contained in a system. It's formulated by pointing out the change in internal energy in system minus work and heat that add and subtract energy in the system. Moreover, the second law helps to clarify different ways in which motors change heat into mechanical work, for example in steam turbines and car engines. The third law, also referred to as Nernst law, provides a basis for calculating absolute entropy value of substances and an analysis of phase and chemical equilibrium.
