PHYS 2110 - General Physics I

Homework Instructions & Study Guide

HOMEWORK INSTRUCTIONS

Students:

1.     Go to  http://saplinglearning.com

2.     a. If you already have a Sapling Learning account, log in then skip to step 3.
b. If you have Facebook account, you can use it to quickly create a SaplingLearning account. Click the blue button with the Facebook symbol on it (just to the left of the username field). The form will auto-fill with information from your Facebook account (you may need to log into Facebook in the popup window first). Choose a password and timezone, accept the site policy agreement, and click "Create my new account". You can then skip to step 3.
c. Otherwise, click "Register here". Supply the requested information and click "Create my new account". Check your email (and spam filter) for a message from Sapling Learning and click on the link provided in that email.

3.     Find your course in the list (you may need to expand the subject and term categories) and click the link.

4.     Select your payment options and follow the remaining instructions.

5.     Once you have registered and enrolled, you can log in at any time to complete or review your homework assignments.

During sign up - and throughout the term - if you have any technical problems or grading issues, send an email to  support@saplinglearning.com  explaining the issue. The Sapling support team is almost always more able (and faster) to resolve issues than your instructor.

EXAM 1

VECTORS 

Representation of vectors

  • Graphic representation
  • Graphic definition of operators
  • Linear space and basis:   (3D) a = a1*e1 + a2* e2 + a3*e3
  • Coordination system
  • Polar/spherical coordinates: 2D (r, θ), 3D (r,θ, φ)
  • Cartesian coordinates: (x,y,z)

Operators of vectors

  • Unary operator:   +A, -A, etc.
  • Binary operator:  A+B, A-B, αA, A·B, A × B, A∧B, etc.
  • Operators definition using graphic representation and Cartesian system

KINEMATICS

  • Position described as vectors: relative to coordination system
  • Displacement:
  • Velocity:
  • Acceleration:
  • Kinematic models for point
  • constant acceleration motion
  • uniform circular motion

EXAM 2

Point-Mass Model

  • Newton's three laws of motion
  • Define inertial reference frame which the laws are based upon.
  • Pair-wise only interaction picture
  • Time-reversal symmetry
  • Energy, Work
  • Conservative Force/Potential Energy
  • Work-Energy Theorem/Newton's Second Law
  • Momentum, Impulse
  • Momentum-Impulse Theorem/Newton's Third Law

EXAM 3

Many Points-Masses Model

  • Descriptions
  • Total mass M=sum(mi)
  • Center of mass   rcm=sum(mi*ri)/M
  • Velocity and acceleration of center of mass:
  • Center of force  rcfxsum(Fi) = sum(rixFi)
  • Total momentum:  Pnet = sum(mixvi)
  • Total kinetic energy:  Knet=sum(1/2*mi*v2i)
  • Translational kinetic energy:  KT=1/2*M*v2cm
  • Newton's Laws of Motion
  • Second law:     dPnet/dt = Fnet
  • Third law: for an isolated system,    Pnet=const
  • Work-Energy Theorem for many points-masses model
  • Momentum-Impulse Theorem for many points-masses model

Special case: rigid body

  • Description:Kinematic models:
  • Constant angular acceleration motion
  • Precession (constant magnitude of angular acceleration)
  • Special case: elasticity
  • Special case: fluid
