Document Summary

categorical imperative: i shall never act except in such a way that i can also will that my maxim become a universal law. this is basically saying that one should never act unless your maxim will become a universal law. this is the formula of the universal law. example: in order to get out of trouble, i will make a promise that i don"t intend to keep. (goal) (action/means) For kant, being evil is making exceptions to rules. There are 3 kinds of categorical imperatives: (1) formula of universal law: i shall never act except in such a way that i can also will that my maxim become a universal law. in other words, treat each person with the appropriate respect. example: promising to pay someone back their money and actually keeping that promise. You can treat someone as a means (only if showing them the proper respect)

Planetary motion.

A planet or asteroid the sun in an elliptical path. The diagram shows two points of interest: point P, the perihelion, where the planet is nearest to the Sun, and the far point, or aphelion, at point A. At these two points (and only these two points), the velocity v of the planet is perpendicular to the corresponding "radius" vector , from the Sun to the planet. An arbitrary point Q is also shown.

Suppose the asteroid's speed at aphelion is , and its distance from the sun there is (AU is the "astronomical unit", commonly used in planetary astronomy).

a) Determine the planet's speed at perihelion.

b) Determine the planet's distance from the Sun (in AU) at perihelion.

Assume that the Sun is orders of magnitude more massive than the asteroid. This means the Sun does not accelerate significantly in response to the planet's gravity and can be assumed to remain at rest.

Derive a symbolic formula, but don't try too hard to simplify it. Look up the values and conversion factors you need in order to obtain a numerical answer.

Recall the universal gravity formulas:

Force

potential energy

Consider the Sun-asteroid system to be isolated and apply conservation of energy.

I'm starting a Physics course which uses "Physics for Scientistsand Engineers 8th Edition". The most advanced Math I've taken isPrecalculus (functions and trig). I'm taking Cal 1 at the same timeas this Phys and would like to know if I should skip the Phys andwait until I've learned Cal. The Physics book consists of thefollowing:

Part 1: Mechanics
1 Physics & Measurement
2 Motion in One Dimension
3 Vectors
4 Motion in Two Dimensions
5 The Laws of Motion
6 Circular Motion & Other Applications or Newton's Law
7 Energy of a System
8 Conservation of Energy
9 Linear Momentum and Collisions
10 Rotation of a Rigid Object About a Fixed Axis
11 Angular Momentum
12 Static Equilibrium and Elasticity
13 Universal Gravitation
14 Fluid Mechanics

Part 2: Oscillations and Mechanical Waves

15 Oscillatory Motion
16 Wave Motion
17 Sound Waves
18 Superposition and Standing Waves

Part 3: Thermodynamics

19 Temperature
20 The First Law of Thermodynamics
21 The Kinetic Theory of Gases
22 Heat Engines, Entropy, and the Second Law ofThermodynamics

Sorry about the length but it's an important decision for me. Thankyou.
