Answer 2

Space and Time, Matter and Change, Forces and Motion, Energy

Question 3

1st law of thermodynamics: energy

Answer 3

energy cannot be created or destroyed it just changes form

Question 4

2nd law of thermodynamics: energy/things

Answer 4

go from order to disorder unless work is done

Question 5

3rd law of thermodynamics: absolute

Answer 5

absolute zero cannot be reached

Question 6

Law of conservation of momentum : if no net

Answer 6

if no net force acts on a system then energy is conserved

Question 7

Four of five states of matter: S,L,G,P

Answer 7

Solid, Liquid, Gas, Plasma

Question 8

Newton’s 1st law of motion: An object

Answer 8

An object at rest stays at rest and an object in motion stays in motion unless a force acts upon it

Question 9

Newton’s 2nd law of motion: force equals(F=MA)

Answer 9

Force equals mass times acceleration

Question 10

Newton’s 3rd law of motion: For every

Answer 10

For every action there is an equal and opposite reaction

Question 11

Law of conservation of matter: Matter

Answer 11

Matter cannot be created or destroyed it just changes form

Question 12

Law of conservation of mass and energy: (E=mc^2) Energy equals

Answer 12

Energy equals mass times the speed of light squared

Question 13

Difference between law and theory

Answer 13

A law has been tested over and over, a theory connects many laws and creates an explanation
