Newtons 1st Law
objects will not accelerate unless an external force acts upon it
1 of 35
Newtons 2nd Law
accelration is produced whena force acts on a mass F = ma
2 of 35
Newtons 3rd Law
for every action there is an eqaul and opposite reaction
3 of 35
WHy doesn't a boat witha fan move?
-both forces, air on fan and air on sail are equal -no resultant force (newtons 1st law) -no acceleration (newtons 2nd law)
4 of 35
Why are the fast samples the most innacurate
they are proportionally more affected by reaction times
5 of 35
Fat + Protein
lipoprotein (+LDL and -HDL)
6 of 35
LDL
-bind to cell receptors -block receptors -increase cholesterol deposit on artery walls -from sat fat
7 of 35
HDL
-higher % of protein -take cholesterol to liver to be broken down -removes fatty plaques -from unsat fat
8 of 35
Lipids and Solubility
they are not soluble in water but they are soluble in organic solvents (ethanol)

16 of 35
Work is not a vector/scalar
vector quantity
17 of 35
Force is a vector/scalar
scalar quantity
18 of 35
Order of points on stress strain graph
limit of proportionality, elastic limit, yeild point, tensile strength
19 of 35
A stopwatch isn't reliable because
-human error -different people -different reaction times
20 of 35
When only one light gate is used
-measure the length of the trolley -meausre time taken to pass
21 of 35
Young Modulus of a Wire Experiment (apparatus)
-arrangement to secure wire -arrangment to hold different forces
22 of 35
Young Modulus of a Wire Experiment (how to measure)
-micrometer for diameter -length with ruler -force by adding known weights -extension with ruler
23 of 35
Young Modulus of a Wire Experiment (how to calculate)
-plot stress strain graph -determine gradient of graph
24 of 35
Young Modulus of a Wire Experiment (precautions)
-measure the diameter in multiple places -it will vary
25 of 35
Elastic Limit
the wire begins behaving plastically
26 of 35
