Can mass be transformed into energy and vice versa and if so why does this not follow the conservation of mass and energy?

Transformation of energy does follow the conservation of mass and energy. When a body gains potential energy, it loses kinetic energy and viceversa. Therefore total energy always remains constant.

Why can the law's name be Conservation of Matter or Conservation of Mass and still be the same?
In both cases, something is conserved - it doesn't change over time.Also, mass and energy are equivalent. If something has energy, it has mass, and vice versa.
How does Einstein's equation Emc2 seem to contradict the law of conservation of mass?
E=mc2 demonstrates that matter can be changed into energy and vice versa, which would appear to mean that matter can be created and destroyed. A way around this would be to consider mass and energy as part of the same value.
What are the primary ways that heat energy transformed through the earth's system?
Convection. Most of the heat is transferred from hot air heating the ground/water, or vise versa. The heat originally comes to earth from radiation from the sun, but once here, convection is how it is moved around.
How is the law of conseervation of energy illustrated by newtons cradle?
Newton's cradle conserves energy but converts it from potential to kinetic energy and vice versa.
How do you conserve energy?
AnswerThere are two answers to consider here - the laws of energy conservation, and the colloquial concept of conserving energy.Law of Energy Conservation (Physics)The law of energy conservation states that the total amount of energy in a classical closed system remains constant. This means that energy may never be created nor destroyed. Energy can be converted - such as light may irradiate a surface, and the absorbed light is converted into thermal energy, thereby heating the surface. Similarly, electrical energy in a motor may be converted into mechanical energy. In these examples, while energy is converted from on form to another, the total amount of energy in the system forever remains constant.In quantum mechanics, mass and energy are transferrable - meaning mass can be converted to energy, and vice versa. This conversion process takes place in accordance with the famous Einstein equation ofE = mc2where 'E' is the amount of energy (in Joules) and 'm' is the mass (in Kg), and 'c' is the constant speed of light (in m/s). This equation predicts with exact precision the amount of energy liberated when mass is converted into energy, or conversely, the amount of energy required to convert energy into mass. Such mass-energy conversions take place in celestial stars, atomic reactors, and nuclear bombs.In the mass-energy conversion, it is conceivable to consider mass as another form of energy. When this principle is applied, then the laws of energy conservation still hold - meaning that while mass and energy may be converted back and forth, the total amount of mass/energy remains constant in a given system.Conserving Energy (Society)Energy conservation is a social concept in which individuals, including citizens, companies, governments, institutions, and other organizations, strive to reduce the amount of commercial energy they consume. While each individual's contribution to energy conservation may be miniscule, the cumulative effect of all individuals each conserving a small amount of energy has proven to yield dramatic results on the macro scale. In such conservation efforts, individuals reduce the amount of fossil fuels and/or electricity they consume.All energy conservation efforts fall into one of two categories - direct and indirect. Direct conservation efforts seek to alter people's lifestyles and behaviors in a manner that reduces the total amount of energy consumed. Direct energy conservation leads to a reduction in energy consumption only while the modified behavior persists - the energy conservation benefits cease as soon as the person returns to the pre-conservation behavior. An example is remembering to always turn the lights off when not in a room, or setting the thermostat in the winter to 68o instead of 72o. Both these activities directly lead to a reduction in the consumption of electricity and/or fossil fuels only as long as the conservation activities continue.Indirect energy consumption efforts are one-time measures that lead to a sustained reduction in electricity and/or fossil fuel consumption. Replacing incandescent light bulbs with compact fluorescent light bulbs is done only once, however this measure leads to a sustained reduction in electricity consumption. Choosing to purchase a more fuel efficient automobile is another example of a one-time indirect energy conservation measure that returns lasting conservation effects.Indirect energy conservation may take many forms. Energy recovery, for example, occurs in many industrial and commercial settings in which previously "wasted" energy is now re-used for other purposes. A blast furnace's hot exhaust, for example, was typically vented to the outside environment. Now the exhaust heat is reclaimed using an energy recovery system, and that recovered energy is used to make steam that drives turbine driven electricity generators. Some hybrid vehicles also recover energy by converting the car's kinetic energy (motion) back into electrical energy when the driver coasts or applies the brakes. A non-hybrid car dissipates (wastes) this kinetic energy as thermal friction, whereas the energy-recovery equipped hybrid vehicle converts and stores some of the kinetic energy for later use as electricity.Technology offers a direct-to-indirect solutions in many energy conservation scenarios. For example, a homeowner can install a programmable thermostat that regulates the temperature based on the living patterns. Offices may install motion sensors that automatically turn off lights when no one occupies a room. In these cases, technology supplants human behavior modification, often with more reliable energy conservation results.At the social scale, a community must practice both direct and indirect energy conservation methods to minimize energy consumption. A city may install a fuel efficient mass transportation system, for example (an indirect effort), but it must also convince its denizens to stop driving their cars to work every day, and start commuting on the mass transit system (a direct effort). Some jurisdictions impose measures to modify energy consumption behavior. London and Hong Kong, for example, regulate or tax the use of vehicles for commuting purposes. Similarly, many regions in North America charge consumers a premium for consuming electricity during peak load periods.
How does the law of the conservation of energy pertain to kinetic and potential energy?
The Law of Conservation of Energy states that energy can not be created or destroyed, it can only be transformed. So, kinetic energy is not created, it is transformed from potential energy, and vice versa.
Can energy be transformed into matter and vice-versa?
Once the mass is known, so is the energy, and vice versa. So yes it can be transformed both ways.
How are the laws of conservation of energy and the law of conservation of mass similar?
In both cases, something is conserved - it doesn't change over time.Also, mass and energy are equivalent. If something has energy, it has mass, and vice versa.

The law of conservation of energy states that when one form of energy is converted to another?
The law of conservation of energy says that energy is neither created nor destroyed only changed. It works hand in hand with the law of conservation of matter, because matter can be converted to energy and vice versa.
Why velocity of a mass attached to a spring is maximum at mean positions and zero at extreme positions?
This can easily be understood with conservation of energy. Assuming that no energy is lost, potential energy is continuously converted to kinetic energy, and vice versa. At the mean position, the potential energy is zero, therefore the kinetic energy (and hence the velocity) is at maximum.This can easily be understood with conservation of energy.

What is the principle of conservation of thermal energy?
There is no such principle. Thermal energy can convert to other forms of energy, and vice-versa. The TOTAL energy (thermal + other kinds of energy) is conserved in a close system.
Why law of conservation of mass should better be called as law of conservation of mass and energy?
Because energy can be converted into mass and vice versa. Thus, while the mass of a system is not conserved in a particular process, the mass and energy of a closed system is always conserved.
What is the difference between conservation of mechanical energy and conservation of total energy?
There is no difference between the two, it's just another way of wording the phrase.
