Unit 8: Energy

Unit 8:  Energy!!!!
           Short Writing for the Unit (Like a chapter from a book)              
                                                                                                                  
                                                         
                                                    
The total energy of the universe is constant; however, the total amount of energy available for useful transformation is almost always decreasing.  Energy can be converted from one form to another and move from one system to another.  Transformation of energy usually produces heat that spreads to cooler places by radiation, convection, or conduction.  Energy can be classified as potential or kinetic energy.  Potential energy is stored energy and includes chemical, gravitational, electrostatic, elastic and nuclear.  Kinetic energy is the energy of motion.  

STANDARD 4:  STUDENTS WILL UNDERSTAND TRANSFER AND CONSERVATION OF ENERGY.
Objective 1:  Determine kinetic and potential energy in a system.
Objective 2:  Describe conservation of energy in terms of systems.
Objective 3:  Describe common energy transformation and the effect on availability of energy.

    • Energy--
      • Kinetic Energy = 1/2 m*v²
      • Gravitational Energy = mgh
      • Elastic Energy = 1/2 k*x²
      • Dissipated Energy = Work done by friction or other forces.  
        • Also, Dissipated energy can be found by finding the difference between the initial and final energies.

      Unit 6 Notes: (Projectile Motion)
      Notes from class:


      See a video tutorial of how to solve a Free Fall Kinematics problem. Click HERE.  (or Here  for a refresher on using Kinematics Equations.)
      See a video tutorial of how to use the Quadratic Formula. Click Here (non-YouTube version)  or Here (YouTube).

      Free fall means an object accelerates only because of gravity. For objects near the Earth's surface, this means that acceleration = 10 m/s². When an object in free fall is thrown upward, its velocity will be zero when it reaches its highest position. When an object is thrown upward and allowed to return to its original height, its displacement will be zero.


      Projectile Motion--think of the amazing basketball shot. We learned that for a projectile, horizontal velocity is CONSTANT, while vertically the object accelerates because of gravity (10 m/s^2 on earth).  To solve projectile motion problems, first split the problem into HORIZONTAL and VERTICAL parts, fill in what you know, use one part of the problem to solve for TIME, and use that time with the other part to solve for what you're looking for.

      See a video tutorial of how to solve a Projectile Motion Problem Involving Angles. Click HERE. 

      Problem Set Solutions can be found on the Physics Files Page. These Problem Sets are based on what we learn each day, and are similar to the online homework. If you are struggling with the online homework, check out the corresponding Problem Set Solution to see in detail how to approach and solve the problems.

      Unit 5 Notes: (Unbalanced Forces, F=ma)
      Notes from class: 

      Newton's 2nd Law: Net Force = Mass x Acceleration. The Net Force can be found by taking R - L, or L - R, or U - D, or D - U. How do you know which one? Take the direction it accelerates to be positive, then subtract forces in the opposite direction. So if something accelerates to the Right, it will be Right minus Left.
      Friction: We learned a formula for determining the amount of friction acting on an object: Ff=(mu)*FN.

      We have learned about Acceleration before--Kinematics. We can use kinematics equations to find acceleration, and then plug that into F=ma

      I created an EPUB version of the notes for this unit. Try it out on your eReader device (Nook, Kindle, iOS device, etc.), and let me know how it worked. File is found in the Unit 5 folder on the Physics Files Page. (There is also a .pdf version that can be viewed/printed from a computer if you do not want to use the eReader format.)

      Problem Set Solutions can be found on the Physics Files Page. These Problem Sets are based on what we learn each day, and are similar to the online homework. If you are struggling with the online homework, check out the corresponding Problem Set Solution to see in detail how to approach and solve the problems.

      Unit 3: Constant Acceleration 2019-2020

      Unit 3 - Constant Acceleration



      Link to video about using the kinematic equations.

      Link to video about graphing kinematic equations.

      Link about how the kinematic equations were derived.
      (You do not need to know this until AP physics, but some of you want to know how)




      Science Benchmark
      The motion of an object can be described by measurements of its position at different times. Velocity is a measure of the rate of change of position of an object.  Acceleration is a measure of the rate of change of velocity of an object.  This change in velocity may be a change in speed and/or direction.  Motion is defined relative to the frame of reference from which it is observed. An object's sate of motion will remain constant unless unbalanced forces act upon the object.  This is Newton's first law of motion.


      Standard 1:  Students will understand how to measure, calculate, and describe the motion of an object in terms of position, time, velocity, and acceleration.
      • Calculate the average velocity of a moving object using data obtained from measurements of position of the object at two or more times.
      • Determine and compare the average and instantaneous velocity of an object from data showing its position at given times.
      • Collect, graph, and interpret data for position vs. time to describe the motion of an object and  compare this motion to the motion of another object.
