Question 1

Radiant energy

Answer 1

Radiant energy is the energy of light (the physical energy resulting from electromagnetic radiation, usually observed as it radiates from a source into the surrounding environment.)

Question 2

Thermal energy

Answer 2

Thermal energy is heat or temperature of an object, all objects have it.

Question 3

Electrical energy

Answer 3

Electrical energy is a type of kinetic energy caused by moving electric charges. The amount of energy depends on the speed of the charges – the faster they move, the more electrical energy they carry. Energy carried by electrical currents (wall sockets.)

Question 4

Mechanical energy

Answer 4

Mechanical energy is energy due to the motion and position of an object.

Question 5

Nuclear energy

Answer 5

Nuclear energy is energy stored in the nucleus of an atom.

Question 6

Chemical energy ​​

Answer 6

Chemical energy ​​is stored energy (potential energy). It is stored in the bonds between atoms and molecules. Chemical energy is what holds the atoms in a molecule together. It also is what holds molecules in a substance together.

Question 7

Law of Conservation of Energy

Answer 7

Law of Conservation of Energy is states that energy can neither be created nor be destroyed. It may be transformed from one form to another. Energy that is stored in chemical bonds.

Question 8

Work

Answer 8

Work is the use of force to move an object. For work to be done, the force must be applied in the same direction that the object moves.

Question 9

Force

Answer 9

Force is an action that changes or maintains the motion of a body or object. Simply stated, a force is a push or a pull. Forces can change an object’s speed, its direction, and even its shape.

Question 10

Potential energy

Answer 10

Potential energy is the stored energy an object has because of its position or state.

Question 11

Kinetic energy

Answer 11

Kinetic energy is the energy of moving matter. Anything that is moving has kinetic energy—from atoms in matter to stars in outer space. Things with kinetic energy can do work.

Question 12

Electrical circuit

Answer 12

Electrical circuit is a closed loop through which electric current can flow. A circuit must include a source of voltage and conductors such as wires to carry the current from the source of voltage and back again.
