Science Test 1 (Energy)

Front 1

Thermal Energy

Back 1

The total energy in a substance (KE adn PE)

Front 2

Force

Back 2

Any influence that can cause an object to be accelerated, measured in newtons in the metric system and in pounds in the British system

Front 3

Potential Energy

Back 3

The stored energy that an object posseses because of it's position

Front 4

First Law of Thermodynamics

Back 4

Whenever heat flows into or out of a system. The gain or loss of thermal energy equals the amount of heat transfered

Front 5

Kinetic Energy

Back 5

Energy of motion possesed by moving objects

Front 6

Mechanical Work

Back 6

Energy that comes from the energy you put in to begin with

Front 7

Second law of thermodynamics

Back 7

Heat never spontaneously flows from a cold substance to a hot substance

Front 8

Equation for PE

Back 8

kg * m * 10

mass * length * acc. of gravity

Front 9

Third law of thermodynamics

Back 9

No system can reach absolute zero

Physicists have been within less than a millionth of 1K, but never 0K

Front 10

Equation of KE

Back 10

1/2 * kg * M^2/S^2

1/2 * mass * velocity^2

Front 11

Formula for Joule

Back 11

kg * M^2/S^2

mass * length^2/time^2

Front 12

What is thermal expansoin?

Back 12

When molecules in a hot substance juggle faster and move further apart

Front 13

Acceleration of gravity

Back 13

The change in an objects speed per time that goes by

10m per second per second

Front 14

What is sublimation?

Back 14

When molecules jump directly from a solid to a gaseous phase

Front 15

Is condensation a warming process?

Back 15

Yes. When gas molecules strike the liquid with increased KE it increases the average KE of the liquid

Front 16

The law of Interta

Back 16

Things _____ to keep doing what they're already doing
