Weight Mass Force
Newtons Laws
N1 - F = 0 then a = 0, v = constant
N2 - Sum F = m x a , a = dv/dt acceleration in the direction of travel, a = v^2/r tangental acceleration
(defines both mass and force)
Units m kg, a ms-2,
applies to a body,
Multipy F= ma by d, d = (v+u)/2 x t
N3 - F12 = -F21,
applies to body contact B1 with B2, a system
Multipy F = ma by t, Ft = I = m(v -u)/t x t , Impulse = change in momentum
Year 12 Concepts
Weight
Symbol: W (vector)
Definition: Force caused by gravity - caused by the proximity to a mass.
Unit: newton N
Weight on Mars, refers to the Normal force measured by scales on the surface of Mars
Mass
Symbol: m, M for a Planet
Definition: Indirect from F = ma, W = mg, (E=mc^2 & Quantum Mechanics)
Unit: kg
gPlanet
Symbol: g for earth on surface (g = 9.8 ms-2), all others require subscript (vector)
Definition: acceleration of a mass on surface of a planet
Unit: ms-2
reaction Force
Symbol: N (vector) - Normal force on a flat surface
Defintion: reading of scales, often called mistakenly weight, N = 0 of freefall is call "weightlessness"
Unit: newtons (N)
g-measured
Defintion: What is recorded by a g measuring apparatus, and will vary from g due to altitude, Moon, Sun, spin of earth, gravitional anomolies
Unit:ms-2
g-force
Definition: N/Wearths surface
Unit: none - a ratio
Humans can only experiance a maximum g-force, g-force = 0 is free fall or weightlessness

Null Hypothesis
A scientific hypothesis is a testable explanation of an observed phenomina http://en.wikipedia.org/wiki/Hypothesis
In development of an argument or line of thinking a hypothesis is a proposition, that has consequences. for instance one can consider several "What if" unrealistic hypothesis.
The orgin of the word put into simple english is " I make the hypothesis" = "I suppose" = "An educated guess"
All scientific experiments produce measurements and data. They are used to test apparatus and techniques, formulate reports, and test hypothesis. So I would argue that not all scientific experiments require hypotheses.
Statistical hypothesis is a term used in the interpretation of statistical relationships between phenomena. In this form there are two sub types of hypothesis. Null and alternative. Null is there is no relationship. The results can prove or disprove the null, or be inconclusive. If the critea is determined after the experiment the experiment is invalid.
MMX was not testing a Statistical Hypothesis, it produced a Null Result which means they measured nothing.
"Null result" means expecting to find something, but after checking everything was plugged in definitely found nothing and disproved the aether wind. http://www.bookrags.com/research/michelson-morley-experiment-wop/

Tide lesson
Write: Tides dot points/ What you know, Importance, Experiance, Cause, Use of energy, Tidal flats.
Hand out the worksheet, and say not to fill in, but write notes, then fill in from book notes
Ask how many tides a day?
Explain
0. Gravity works on Mass, and closeness.
1. Gravity is a force that changes direction of motion into a circular orbit.
2. near moon or sun there is too much and ocean falls towards sun/moon
3. other side gravity too little and matterial would prefer to travel in a straight line into space.
Thus tidal force is a ripping appart force

Take notes to explain as many features as possible.
