Question 1

The potential energy stored in chemical bonds of compounds

Answer 1

chemical energy

Question 2

Work done by moving charges

Answer 2

electrical energy

Question 3

The potential energy stored in the nucleas of an atom, when the nuclei of two in the nucleas of an atom, when the nuclei of two atoms combine this energy released

Answer 3

nuclear energy

Question 4

Flowing water, wind, or any object in motion could be made to work because of its energy is released

Answer 4

kinetic energy

Question 5

The measure of the force of gravitational attraction on an object

Answer 5

Vector Quantity

Question 6

Mass Scalar

Answer 6

Mass can not change

Question 7

(mass)(acceleration due to gravity)(height above ground)

Answer 7

Gravitational Potential Energy

Question 8

9.81m/s^2

Answer 8

Acceleration due to gravity

Question 9

If a force is used to stretch an elastic the force acts against the elastics for the material. This results in change shape of the elastic and the energy being stored

Answer 9

Elastic Potential Energy

Question 10

This energy is stored in bonds of chemical compounds. When a chemical change takes place, the position of electrical charges are alter and energy is released. Any substance can be used to do work through a chemical reaction has potential energy

Answer 10

Chemical Potential Energy

Question 11

Kinetic energy can

Answer 11

be quantified

Question 12

1/2(mass of object)(speed)^2

Answer 12

Kinetic energy equation

Question 13

A general form of energy that is a compound of kinetic energy and potential energy, because they are so compound related

Answer 13

Mechanical Energy

Question 14

Kinetic energy + potential energy =

Answer 14

mechanical energy

Question 15

Potential energy = kinetic energy (vice versa)

Answer 15

Law of Conservation of Energy

Question 16

A weight hung from a fixed point so it can stabilize especially a rod with a weight at the end that regulates mechanism of a clock

Answer 16

Pendulum

Question 17

Hydro-electric dams convert the energy of mobbing water into electricity. A coal burning power station uses many energy conversion to generate electricity

Answer 17

Energy Conversions in Technology in Technological Systems

Question 18

Using the reaction from the splitting of atoms to heat water and turn it into steam, which turns a turbine

Answer 18

Nuclear Energy Conversion

Question 19

Using solar cells to convert the suns energy into other forms of energy

Answer 19

Solar Energy Conversion

Question 20

Opperate like a battery it converts chemical energy in a fuel, like hydrogen, into electrical energy. Unlike a battery it doesn’t require recharging it will produce energy as long as it has fuel. The by products are heat and water

Answer 20

Fuel Cells
