KINEMATICS & NEWTON'S LAWS OF MOTION
That shortest distance between two points measured from a fixed frame of reference?
What is displacement?
The application of a force applied in the same direction as the displacement.
What is work?
Motion in a circle at a constant speed.
What is Uniform Circular Motion?
U it the TOTAL Energy including both PE plus the total random KE of all the particles in a gas, where as T is a measure of the AVG KE.
What is the difference between thermal energy and internal energy?
Light shifts towards the red end of the visible spectrum.
What is the effect of the Doppler effect on the color of stars and galaxies that are moving away from Earth?
The fastest speed reached by a free falling object under influence of gravity and air resistance.
What is terminal speed?
The sum of kinetic and potential energy acting on a mass where friction is negligible.
What is mechanical energy?
When putting a satellite into orbit (ignoring friction) the total energy minus the kinetic energy equals this.
What is gravitational potential energy?
What is Heat Capacity?
longitudinal sound waves that have resonant/natural frequencies given by 2n/4L where n = 1, 3, 5,...
What is closed pipe resonance?
Rate of change in momentum acting on a mass.
What is Newton's 2nd Law of motion?
Energy does not get created and it is never destroyed, it is transferred or transformed.
What is the law of conservation of energy?
g=F/m
What is Gravitational Field Strength?
temperature, surface area and air flow
What are the three main factors that affect the rate of evaporation?
Gases that oscillates at the same natural frequency as the infrared radiation emitted from the surface of earth.
What are green house gases?
Speeding up in the wrong direction describes this type of motion.
What is negative acceleration?
A principle that describes the proportional relationship between a force applied to an elastic mass and its displacement from rest.
What is Hooke's Law?
F=G Mm/r^2
What is Newton's Law of Universal Gravitation?
A hypothetical type of gas that follows all gas laws.
What is a Ideal Gas?
A substance that polarizes light a second time.
What is an analyzer?
The area of a Force vs Velocity function.
What is power?
Power out versus total power in.
What is <Work> Efficiency?
Lines indicate surfaces with a constant amount of energy per unit mass [J/m]. They are perpendicular to field lines and their spacing affects how gradient in field strength of changes.
What are equipotential lines?
A fixed pressure gas where the Volume and Temperature are directly proportional to one another.
What is Charles's Law?
An image of two sources of light will be just resolved when the central peak of one diffraction pattern lines up with the first minimum of the second diffraction pattern.
What is the Rayleigh criterion?
