Velocity-Time Graphs

Before Class Preparation:

  • Finish Non-Uniform motion handout
  • If possible, print this worksheet and
    • Complete Part A (Remember these are Velocity-Time Graphs)

In Class Practice:

  • PollEV Discussions for motion
  • conduct an inquiry into the uniform motion of an object
  • solve problems involving uniform linear motion in one dimension using graphical analysis
    • Using Motion Sensors to investigate v-t graphs
    • PollEV Discussions

After Class Work:

  • Answer questions on Google Classroom
  • Read & take notes on this Powerpoint if you like taking notes

Quiz – Standing/Sound Waves

Before Class Preparation:

  • Finish Assigned Braingenies & Self Quizzes

In Class Work:

  • 15 minute group discussion
  • 30 minute quiz: Application of Standing/Sound Waves

Can you:

  • Determine a wave’s period & frequency when given a graph of the wave.
  • Calculate the frequency of a standing wave in a medium that is:
    • Open at both ends
    • Closed at both ends
    • Open at one end
  • Calculate the speed of sound from a standing wave patterns in an air column closed at one end.
  • Draw a standing wave pattern for an air column or string instrument and
    • Calculate frequencies/lengths of the instrument
  • Describe and calculate how sound changes (frequency, wavelength, velocity) through different mediums

After quiz:

Take up the quiz immediately using Sage & Scribe 

Non-uniform motion (Multiple Days)
