Question:

gravitational potential energy

Answer:

· Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be constant at about 9.8 m/s2.

Question:

Kinetic energy

Answer:

The kinetic energy (KE) of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Question:

Chemical Energy

Answer:

· Chemical energy is energy stored in the bonds of chemical compounds, like atoms and molecules. This energy is released when a chemical reaction takes place. Usually, once chemical energy has been released from a substance, that substance is transformed into a completely new substance.

Question:

Enerfgy conversion/transformation

Answer:

· the process of changing one form of energy to another. In physics, the term energy describes the capacity to produce certain changes within a system, without regard to limitations in transformation imposed by Entropy.

Question:

Efficiency

Answer:

· Efficiency is a measure of how much work or energy is conserved in a process. In many processes, work or energy is lost, for example as waste heat or vibration. The efficiency is the energy output, divided by the energy input, and expressed as a percentage. A perfect process would have an efficiency of 100%.

Question:

The law of conservation

Answer:

· The law of conservation of energy is a physical law that states energy cannot be created or destroyed but may be changed from one form to another.Another way of stating this law of chemistry is to say the total energy of an isolated system remains constant or is conserved within a given frame of reference

Question:

Density

Answer:

· Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).

Question:

Atmospheric pressure

Answer:

· Atmospheric pressure is a force in an area pushed against a surface by the weight of the atmosphere of Earth, a layer of air. ... This is because high places do not have as much air above them, pushing down. Barometers can be used to measure atmospheric pressure. There is the same atmospheric pressure from all directions.
