Classical Mechanics: Essentials Flashcards
What is Newton’s Second Law?
Newton’s Third Law
If two bodies A and B interact, the force that A exerts on B is identical in magnitude and opposite in direction to the force B exerts on A
Define work
Define (classical) translational kinetic energy
Define power
Power is work per time.
Give a description of power along a straight line or in rotational systems
Spring potential energy
Near-Earth gravitational potential energy
Nonrelativistic momentum
Collisions conserve:
All collisions conserve momentum. Fully elastic collisions conserve energy as well. Inelastic collisions do not conserve energy.
Center of mass
Change in velocity of a rocket after expulsion of a given mass of fuel
Center of mass velocity
Define pressure
What is the gravitational field of a point mass?
What is Kepler’s 1st law?
Each planet moves in an elliptical orbit with the sun at a focus.
What is Kepler’s 2nd law?
A line from the sun to a given planet sweeps out equal areas in equal times.
What is Kepler’s 3rd law?
The periods of the planets are proportional to the 3/2 powers of the major axis lengths.
Angular frequency of a simple pendulum
Effective spring constant in parallel and series
Spring constants add in parallel. Their inverses add in series.
Kinematic equation 1 (position as a function of time given constant acceleration)
Kinematic equation 2 (quadratic bypass)
Kinematic equation 3 (change in position with unknown acceleration)
Kinematic equation 4 (final velocity without reference to position)
