Physics

Fall Semester Exam Topics

Exam Week Tuesday, December 15th - Friday, December 18th

The exam is comprised of 20% first nine-week material and 80% second nine-week material.  An exam review will be handed out Monday, December 14^th. Students will be chosen to present topics during the study periods. Please see the exam topics and the exam schedule below.

First Nine-Week Topics

Safety in the Physics Lab

Measurement Skills

Units of Physics

Significance – define & apply

Accuracy v.Precision – differentiate/apply

Scientific Notation

Dimensional Analysis & Conversions

Hypothesis, Theory, Law

Scientific Method terminology & procedures

Independent v. Dependent Variables

Graphing Techniques

Newton's Three Laws of Motion - define & apply

Graphing & Interpreting: Velocity, Acceleration, Force

Problem Solving & Critical Thinking:

  Velocity  v = d/t  m/s

  Acceleration  a = v/t   m/s^2

  Force  F = ma  N (newton)

  Momentum  p = mv   kg-m/s

  Free Fall  d = 1/2 x a x t^2  m (meters)

Mass v. Weight

Scalar v. Vector Quantities

Discuss Egg Drop Project concepts, purpose, & results

Second Nine-Week Topics

Types of Forces - differentiate between types of forces

Force v. Net Force

Balanced v. Unbalanced Forces

Trigonometry of Right Triangles: Use of Pythagorean Theorem & sine, cosine, & 

   tangent

Vector Analysis

  - Vector Addition (use Pythagorean Theorem to determine resultant and tangent to find direction in degrees)

  - Vector Resolution (resolving resultant vector into its x and y components using SOHCAHTOA)

Multiple Vector Analysis

  - Determine one resultant vector to replace all other vectors pulling on Point P; 

  - Determine its acceleration; 

  - Determine the equilibrant vector that stops resultant vector's acceleration.

Two-Dimensional Projectile Motion

  - Range  horizontal displacement = horizontal velocity x total time

  - Max Height = 1/2 x g x t^2 (t = time up)

  - Time Up = vertical velocity / gravity

  - Vertical Velocity =  Initial Velocity x sine theta

  - Horizontal Velocity = Initial Velocity x cosine theta

Work  A form of energy (energy is abiliy to do work)

  - Linear Work = force x displacement (no movement, no work)  Label is J (joules)

  - Angular Work = force x cosine theta x displacement

Power  

 P= Work/time = Fd/t = F(cos theta)d/t = Fv    Label is W (watts)

Mobile Project - discuss application of Work concept to the project/apply to 

     other scenarios
