Chemical potential

In class today we dropped a racket ball beneath a sensor in order to describe the motion of the ball in free fall. We collected our data through a sensor that determines the distance of an object from its current location. The sensor connects to a LabQuest that connects to the program Logger Pro, which copies the data collected and forms a position versus time graph as well as a velocity versus time graph. In order to have the data fit the situation of the bouncing ball, we zeroed the sensor so…

Abstract The value for the acceleration of gravity was measured in this report through the investigation using three different methods, each varying in accuracy, to calculate the period of a pendulum. The period was measured by repeatedly timing the time it took for the pendulum to return to its original position once it was swung from a certain point (for the first method one oscillation was timed, however in the second and third ten oscillations were timed and the overall time was divided by…

time, and learning about the process made me realize how much needs to happen for me to feel a certain way or perform a certain action. In a neuron, it first has to have a certain amount of depolarizing ions for there to be an action potential. When that action potential is reached, charge can be sent through the axon (which is protected by the myelin shealth). As a charge goes through a neuron, vesicles that hold neurotransmitters (that are contained in the presynaptic terminal button) can be…

spaces that are uncovered by the myelin sheath. Once the neural impulse reaches the end of the axon, the neural impulse is now at the terminal button, also known as the axon bulb. The axon bulb contains many neurotransmitters. Neurotransmitters are chemicals that relay messages to another neuron between the synapses, the space between the axon bulb and the dendrites of another neuron. The synaptic gap does not come in contact with one another. The area where the neurotransmitters are released is…

can not be created or destroyed only converted into different forms and traded between systems. All energy is measured in Joules (J). When we talk about waterfalls and dams, the energy’s original form is Gravitational Potential Energy (GPE) which is energy that comes from the potential all objects have to move due to gravity when they are not on the surface of the Earth. The GPE of an object is just the relationship between the object’s mass, the acceleration due to gravity which is a…

Hydropower is power that is generated from a dam by making water fall from a certain height behind the dam to a power plant that is lower in height. As a result, the water behind the dam has gravitational potential energy, which is converted to kinetic energy as it falls to the power plant. The power plant uses its turbines to convert the kinetic energy to electrical energy. In this assignment, we are figuring out “to what extent can hydropower meet the electrical energy needs in the United…

(The nervous system Louisa Idzal) The nervous system is all connected because it’s a web of nerve cells and fibers that all send nerve impulses throughout and between body parts. The nervous system is really important because it’s in charge of sending messages to the spinal cord and brain to and from all parts of the body. Main organs of the nervous system are Nervous Tissue, Brain, Spinal Cord, Nerves, Sense Organs, and the Cerebrospinal Fluid. The nervous tissue is the main tissue of the…

1. What energy system(s) does the Wingate Test rely? Explain. The energy systems that the Wingate test relies on, is glycolysis and ATP-PCr. Anaerobic power is used for high intensity, short duration exercises, and activities. The Wingate test is anaerobic, which will utilize fuel through glycolysis and the ATP-PCr system. The Wingate test is very short in duration, and high in intensity, which means oxygen is not present in this process. The ATP-PCr system breaks down ATP into ADP for energy.…

surface at an angle, the more potential she will have for flips. You can find a gymnast’s angular momentum with the formula: L = (r)(m)(v). By analyzing the equation, you can determine that, while the mass (m) and angular momentum (L) are considered a constant, lowering the distance of the body from the axis of rotation (r), will lead to an increase in velocity (v), this velocity allows for the gymnast to attain the maximum amount of force, leading to more potential for twists and flips while in…
