Q

What is Newton’s Second Law?

A
2
Q

Newton’s Third Law

A

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

3
Q

Define work

A
4
Q

Define (classical) translational kinetic energy

A
5
Q

Define power

A

Power is work per time.

6
Q

Give a description of power along a straight line or in rotational systems

A
7
Q

Spring potential energy

A
8
Q

Near-Earth gravitational potential energy

A
9
Q

Nonrelativistic momentum

A
10
Q

Collisions conserve:

A

All collisions conserve momentum. Fully elastic collisions conserve energy as well. Inelastic collisions do not conserve energy.

11
Q

Center of mass

A
12
Q

Change in velocity of a rocket after expulsion of a given mass of fuel

A
13
Q

Center of mass velocity

A
14
Q

Define pressure

A
15
Q

What is the gravitational field of a point mass?

A
16
Q

What is Kepler’s 1st law?

A

Each planet moves in an elliptical orbit with the sun at a focus.

17
Q

What is Kepler’s 2nd law?

A

A line from the sun to a given planet sweeps out equal areas in equal times.

18
Q

What is Kepler’s 3rd law?

A

The periods of the planets are proportional to the 3/2 powers of the major axis lengths.

19
Q

Angular frequency of a simple pendulum

A
20
Q

Effective spring constant in parallel and series

A

Spring constants add in parallel. Their inverses add in series.

21
Q

Kinematic equation 1 (position as a function of time given constant acceleration)

A
22
Q

Kinematic equation 2 (quadratic bypass)

A
23
Q

Kinematic equation 3 (change in position with unknown acceleration)

A
24
Q
