the calorie

is defined as the amount of energy required to raise the temperature of 1 g of water from 14.5C to 15.5C


Potential Energy

Stored energy


Kinetic Energy

the energy or motion


Measurement Units in Medicine

MASS
1 milligram(mg)= 1000micrograms (mcg 1 grain (gr)= 65 milligrams(mg) VOLUME 1 cubic centimeter(cc or cm3)= 1 milliliter (mL) 15 drops(gtt)= 1 milliliter(mL) 1 teaspoon (tsp)= 5 milliliters (mL) 2 tablespoons(T or tbsp)= 1 ounce (oz) 1 mL=1x.001 L 

Significant figures
Multiplication Division 
calculations should not change the degree of uncertainty in a value.
When doing multiplication or division with the measured values, the answer should have no more significant figures then any number used in the calculation. 

Significant figures
Addition 
when doing addition or subtraction with measured values, the answer should have the same number of decimal places as the quantity with the fewest decimal places


Scientific notation

an exponent with a positive value tells you how many times to multiply a number by 10
an exponent with a negative value tells you how many time to divide a number b 10 

Temperature concersions

f=(1.8xc)+ 32
c=f32/1.8 

accuracy

is related to how close a measured value is to a true value


precision

is a measure of reproducibility


Measurement Units

1 kg= 2.205 lbs
1 kg= 100 g 1 m= 3.281 ft 0.946 L= 1 qt 1 m3= 1000L 4.184 J= 1 cal F=(1.8xC) + 32 C= F32/1.8 K=C + 273.15 

exact numbers

have an unlimited number if significant figures


significant figures

those digits in a measurement that are reproducible when the measurementis repeated, plus the first doubtful digit


the scientific method

the process used to gatherand interpret information. observation is part of the process


laws

are statements that describe things that are consistently and reproducibily observed


hypothesis

a tentative explanation that is based on presently known facts.


theory

an experimentally tested explanation of an observed behavior


matter

is anything that has mass and occupies space


physical properties

characteristics that can be determined without changing the chemical composition of matter (what it is made of)
