A Spring Said To Be Elastic While Putty Is Inelastic
1. What is the law of the conservation of energy? Who is credited for its formulation? The law of the conservation of energy has many parts. It states “…energy is neither created nor destroyed. Energy may be transferred from one object to another, but the total amount of energy present remains constant. The amount of energy present is never increased or decreased by any process. The present energy can only change by transferred energy to or from the system it is in” (Musiek & Sahley, 2015, p. 67). A great example of this process is heat (thermal) energy. Energy through heat can be transferred by convection, conduction and radiation. A great example is a metal pot sitting on the stovetop. The heat from the eye of the stove is transferred …show more content…
It is still energy focused, but with added interest in heat, hence “thermo.” The law of the conservation of energy has also proven to exhibit construct validity; by applying to different types of energies and energy transfers.
2. Why is a spring said to be elastic while putty is inelastic? Elasticity is the ability for objects to change their shape or size temporarily and not break when a force is applied. Elasticity has something known as a “restorative force,” which allows the same objects that change size and shape to return to their previous shape. Common examples of elastic objects are springs, rubber bands, and water.
From another perspective we have inelastic objects. Inelastic and elastic objects follow the same guidelines. However, when the force is removed from an inelastic object it doesn’t return to its previous shape like an elastic object wood. Some common examples of inelastic objects are play dough and putty.
A spring is considered elastic because it expands and then returns to the exact size and shape it was before it was stretched. While putty on the other hand, is removed from the container in one shape. Then, it is manipulated into several other shapes. Furthermore, when the restorative force is removed the putty does not return to it’s original

Another source is electric discharge which is light produced when an electrical current passes through air or another, like neon, that produces a glow. Another source is light-emitting diode which is light produced when an electrical current passes through a semi-conductor which controls how well is conducts electricity.

1286 Words | 6 PagesKinetic energy is moving energy and can be found through the equation KE=(½)mv². Energy is measured in the units of Joules or j. Potential energy is another form of energy that is energy that has the ability or potential to make matter move once it is released. Energy cannot be destroyed or created, rather is is transformed into other types of energy (for example kinetic to electrical). Mass is also another type of energy (mass energy) and it is just the mass of an object or the energy of being. Chemical changes cause atoms to be altered or changed while physical changes do not affect the chemical state of an object.

Reactions require collisions between reactant molecules or atoms. In chemical reactions, the reactants change into products when molecule collide with enough energy to break old bonds to make new ones. Collisions increase or become more violent between molecules at higher temperatures or decrease as the temperature is lowered.

The Law of Conversation of Energy states that the quantity of energy remains continuous. Therefore, the energy that is certainly lost in friction throughout seeking to move an item is actually taken on heat energy. Your friction associated with elements rubbing collectively produces heat. Friction also makes movement of objects difficult.

Elasticity means the ability of an object to resume its normal shape after being stretched, or the ability of something to change and adapt. Some examples of elasticity is a bungie cord and rubber bands. Then there things that can be the opposite of elastic; which is called inelastic.
Examples Of Newton's Laws Of Motion
733 Words | 3 PagesJust How Simple are Newton’s Laws of Motion By Kevin Carver It was an Englishman named Isaac Newton who developed the three laws of motion that laid the foundation for classical physics. He published them in a 3 volume work in 1687. In this article we will look at each of the three laws in simple terms and provide evidence supporting the laws together with examples of how each law impacts our daily lives. Newton 's first law Newton 's first law states that an object will stay at rest if there is no external force being applied, and that an object will stay in motion with the same speed and direction unless an external force is applied.

The force being even or balanced will not result in movement. An unbalanced force is when 2 separate forces are acting on one object, but one force is stronger. The next force is friction.

613 Words | 3 PagesThe 1st law is the law of inertia. This law stated that an object at rest stays at rest and an object in motion stays in motion unless acted on by and unbalanced force. The 2nd law is the law of Mass and Acceleration. This law stated that the greater the mass of an object the more force needed to move it. This is equal to Force = Mass x Acceleration.

Lately our energy sources on the planet are becoming scares; therefore scientists are busy researching new ways to make energy available for our everyday use. There are many different kinds of energy in the universe, one of the most recent and closest is the sun, which seems to be an unlimited source of energy. The energy coming from the sun lights the sky and to an extent warms the whole ecosystem. This enormous type of energy from the sun is called nuclear energy.
