- Block 0 - Physics will be part of the Block 0 exam, which will be held from December 1-5, 2021.
Lectures and Final Exam
- Lectures are available through Blackboard Learn.
- The online exam for Block 0 will be on Blackboard Learn.
- Online proctoring will be used for the exam.
Physics - General Concepts
- The course provides an understanding of physics in the world.
- It helps in understanding different phenomena in everyday life.
- The course explores the physics behind diagnostic and therapeutic techniques, as well as physics in the human body.
- Topics include understanding how devices interface with the human body.
- The course focuses on the application of Physics with minimal mathematics.
- Block 0 – Physics will be covered in ten lectures, with two lectures a day, from November 15 to 19.
- Lectures from 6 PM to 8 PM EST daily, except Thursday (4 PM to 6 PM EST).
- Physics deals with laws of nature, matter, motion, and energy.
- Diagnostic techniques exploit physical phenomena inside the human body.
- Therapeutic Physics and also quantitative analysis of biological systems including the human body will be taught.
Measurements - Units
- The standard MKS system includes meter (m), kilogram (kg), and second (s)
- Other units include ampere, mole, kelvin, and candela.
- Prefixes include: Giga (G) - 10^9, Mega (M) - 10^6, Kilo (k) - 10^3, Milli (m) - 10^-3, Micro (μ) - 10^-6, and Nano (n) - 10^-9
- Examples: 1000 meters = 1 km, 1/1000000 g = 1 μg.
Length
- Length is commonly measured in centimeters (cm), meters (m), inches (in), and feet (ft).
- 1 inch equals 2.54 cm, 1 meter equals 100 cm, and 1 foot equals 12 inches.
- Length can be represented as #’ #” format; for example, 5’ 8” means 5 feet and 8 inches.
Volume
- Volume is measured in cubic centimeters (cm³), cubic meters (m³), cubic feet (ft³), or liters (L).
- 1 cm³ equals the volume of a box with 1 cm sides, also known as cc.
- 1 cm³ = 1 cm x 1 cm x 1 cm.
- 1 L = 1000 cm³ = 10 cm x 10 cm x 10 cm, so 1 cm³ = cc = 1 mL.
Mass
- In physics, mass indicates the quantity of matter in a body (measured in kg), and weight is the force of Earth's attraction (measured in Newton).
- Weight = mass x 9.8
- Mass is measured in kilograms (kg) or pounds (lbs).
- 1 lb = 0.454 kg or 1 kg = 2.2 lbs.
- 1 lb = 16 oz and 1 kg = 1000 gm.
Scalars and Vectors
- Scalars are fully described with a number and a unit. Examples include time, distance, speed, temperature and mass.
- Vectors have directional properties. Examples include displacement, velocity, and force.
- Albany is 224 km (139 miles) West from Boston (displacement).
- The car is heading south at 70 km/h (velocity).
- Gravity is a force.
- Distance from A to B is 25 km (scalar).
- Displacement from A to B is 8 km ENE (East – North East).
- A vector quantity can be represented as 8 km ENE or 5i + 8j.
Electrocardiogram (ECG or EKG)
- The mean QRS vector indicates the direction of total vector of depolarization in the heart and the approximate mean QRS vector may be plotted by averaging QRS deflection in bipolar leads I, II, and III.
- Lead I: Right arm (-), Left arm (+).
- Lead II: Right arm (-), Left leg (+).
- Lead III: Left arm (-), Left leg (+).
- Under normal conditions, the QRS vector points downward to the left, and a deviation reveals an abnormality.
- On ECG paper a small box measures 1 mm x 1 mm and a large box measures 5 mm x 5 mm.
- A small box represents 0.1 mV of potential on the y-axis and 40 ms of time on the x-axis.
- The three bipolar leads create Einthoven's triangle, and perpendiculars can be drawn from the midpoints of each side to find the center of electrical activity.
- The R wave height can be calculated by subtracting the negative deflection in the QRS complex.
- The length of the line, drawn from the center of electrical activity to the intersection of the perpendiculars, represent the magnitude and direction of the mean QRS vector.
