The word stress has been borrowed from Physics and Engineering where it has a precise meaning, A Force sufficient enough in magnitude to distort or deform when applied to a system. For our studies the apt definition of stress would be – ‘the rate of wear and tear of the body.’ (b) The Penguin Medical Encyclopaedia defines Stress as any influence,
Column1 Spring Constant(N/m) Orange 1416.809091 ±193 Light Blue 1387.899091 ±190 Green 1421.951364 ±193 Using that force to find the spring constant from the tweaked equation mentioned before. Conclusion This experiment confirms the relationship of the spring constant between the objects when projected with a certain field of force. Even with their difference in mass, each ball showed similar results when launched with 620 ±80N proving that spring constant has a relationship between if experimented properly. The spring constant of the rubber band in the slingshot I used is on average 1408 ±192(N/m) when the force’s average on each ball is around 620 ±80N. I feel that even with the uncertainties in the numbers from numbers that my answer still contains scientific proof on determining the spring constant.
Newton 's First Law of Motion states that a force must act upon it in order for the motion of an object to change . This is a concept which generally called as inertia. This law also states that if the net force which is the vector sum of all forces acting on an object is zero, then the velocity of the object is constant. Velocity is a vector quantity which indicates both the object 's speed and the direction of its motion. Hence, the statement that states the object 's velocity is constant is a statement that both its speed and the direction of its motion are constant.
Engineers came up with idea of using different types of fluids that can change its property according to the external forces. For example MR (Magneto-Rheological) fluids and ER (Electro-Rheological) fluids. MR fluids are materials that expose a change in rheological properties such as elasticity, viscosity or plasticity with the application of a magnetic field. On the other hand, ER fluids alters its rheological property when an electric field is applied to the fluid. MR fluids require small voltages and current, while ER fluids require very large voltage and very small currents.
Soon, the energy focuses into one wave which becomes significantly larger than those around it. This mechanism can be described by the nonlinear Schrodinger’s equation. One solution to this equation that accurately describes rogue waves is the Peregrine soliton. A soliton is solitary wave that travels like a particle. It maintains a permanent shape when moving at a constant speed and when it collides with another soliton, it emerges with the same speed and shape.
The last 3 results for the Gravitational Potential Energy had values close to the Spring Potential Energy. 4. Conclusion By having relatively close Potential Energy values for the spring and gravity, we could say that the system done in Figure 2 follows the Law of Conservation of Energy, neglecting the friction along the cart. The spring potential energy of the spring plunger was transformed to the gravitational potential energy of the cart. References  Tuckerman, M. E. (2011).
Moreover, the experiment also demonstrated how the different configurations of resistors, parallel or in a series could play a role in the behavior of the circuit and its components. References :  R.

The speed of any wave depends upon the properties of the medium through which the wave is traveling. Typically there are two essential types of properties that affect wave speed - inertial properties and elastic properties. Elastic properties are those properties related to the tendency of a material to maintain its shape and not deform whenever a force or stress is applied to it. A material such as steel will experience a very small deformation of shape (and dimension) when a stress is applied to it. Steel is a rigid material with a high elasticity.
There exists, however, a distinguished scale where one would expect that typical quantum-gravity effects can never be neglected. This scale is found if one combines the gravitational constant (G), the speed of light (c), and the quantum of action (ħ) into units of length, time, mass (and energy).These are called the Plank unit.
“A conservative force is defined as a force with the property that the work done in moving an object between two points is independent of the taken path.” ( Robert A. Pelcovits, 2002) Example of conservative forces in this project is gravitational potential energy. Theoretically, this process could go on forever and the ride would never end if friction and air resistance are ignored. This is because gravitational potential energy is assumed to be transferred completely to kinetic energy and vice
