What is mechanical energy?

• energy stored in an object or system of objects. 

• the energy of either an object in motion or the energy that is stored in objects by their position.

• Energy associated with the motion of an object is called kinetic energy

• the energy contained within a system that is responsible for its temperature.

What is potential Energy?

• energy stored in an object or system of objects. 

• energy that comes from a source and travels through space at the speed of light. 

• degree of hotness or coldness measured by a thermometer with a numerical scale

• Energy associated with the motion of an object is called kinetic energy.

What is temperature?

• result from differences in water density.

• the average kinetic energy of the atoms or molecules of a substance, perceived as how hot or cold it is, and measured in degrees Fahrenheit, Celsius, or Kelvin.

• winds that occur in belts that go all around the planet. 

• the tendency of matter to change in volume in response to temperature alterations.

What is kinetic energy

• result from differences in water density.

• energy that comes from a source and travels through space at the speed of light. 

• Energy stored in an object due to its position is called potential energy.

• a substance which does not readily allow the passage of heat or sound.

What is thermal energy?

• a fast, narrow current of air flowing from west to east that encircles the globe

• the tendency of matter to change in volume in response to temperature alterations.

• the energy of either an object in motion or the energy that is stored in objects by their position

What is Radiation ?

• the tendency of matter to change in volume in response to temperature alterations

• result from differences in water density. 

• energy that comes from a source and travels through space at the speed of light. 

• the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.

What is convection?

• the materials or substances which allow electricity to flow through them

• the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

• fast, narrow current of air flowing from west to east that encircles the globe

• the energy of either an object in motion or the energy that is stored in objects by their position.

What is a conductor?

• the materials or substances which allow electricity to flow through them

• a substance which does not readily allow the passage of heat or sound.

• result from differences in water density.

• from high-pressure areas to low-pressure areas.

What is conduction?

• the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric

• the process by which sound waves travel through a medium.

• degree of hotness or coldness measured by a thermometer with a numerical scale. 

• energy that comes from a source and travels through space at the speed of light.

What is an insulator?

• the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.

• a substance which does not readily allow the passage of heat or sound.

• result from differences in water density.

• the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
