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.

Three of the fundamental constants of physics are the speed oflight, c= 3.0 x 10^8 m/s, the universal gravitational constant,G=6.7 x 10^-11 m^3*kg^-1*s^-2, and Plancks constant, h=6.6 x 10^-34kg*m^2*s^-1
(a) Find a combination of these three constants that has thedimensions of time. This time is called the Planck time andrepresents the age of the universe before which the laws of physicsas presently understood cannot be applied.
(b) Using the formula for the Planck time derived in part (a), whatis the time in seconds?

This problem introduces the concept of tension. The example is a rope, oriented vertically, that is being pulled from both ends. Let Fu and Fd (with u for up and d for down) represent the magnitude of the forces acting on the top and bottom of the rope, respectively. Assume that the rope is massless so that its weight is negligible compared with the tension. (This is not a ridiculous approximation-modern rope material such as Kevlar can carry tensions thousands of times greater than the weight of tens of meters of such rope.)

Consider the three sections of rope labeled a, b, and c in the figure.

  • At point 1, a downward force of magnitude Fad acts on section a.
  • At point 1, an upward force of magnitude Fbu acts on section b.
  • At point 1, the tension in the rope is T1.
  • At point 2, a downward force of magnitude Fbd acts on section b.
  • At point 2, an upward force of magnitude Fcu acts on section c.
  • At point 2, the tension in the rope is T2.

(A) What is the magnitude Fad of the downward force on section a?

(B) What is the magnitude Fbu of the upward force on section b?

(C) The magnitude of the upward force on c, Fcu, and the magnitude of the downward force on b, Fbd, are equal because of which of Newton's laws?

(D) The magnitude of the force Fbu is ______ Fbd.

(E) Now consider the forces on the ends of the rope. What is the relationship between the magnitudes of these two forces?

(a) Fu > Fd

(b) Fu = Fd

(c) Fu < Fd

(F) The ends of a massless rope are attached to two stationary objects (e.g., two trees or two cars) so that the rope makes a straight line. For this situation, which of the following statements are true?

(a) The tension in the rope is everywhere the same.

(b) The magnitudes of the forces exerted on the two objects by the rope are the same.

(c) The forces exerted on the two objects by the rope must be in opposite directions.

(d) The forces exerted on the two objects by the rope must be in the direction of the rope.
