PROJECTILE MOTION & CIRCULAR MOTION


6.1 - Projectile Motion
  • ENGAGEMENT
  • Objectives:
  • Students will explain the concept of projectile motion by recognizing that the vertical and horizontal motions of a projectile are independent, relating the height, time in the air, and initial vertical velocity of a projectile.

  • Warm-up
  • KWL - Projectile
  • EXPLORATION
  • - Video: Big Air
  • - Two students toss a ball back and forth in front of the class. Students will describe the motion as seen from a observer above the motion, and then describe the motion as seen by one of the students doing the tossing...include a sketh in the description.
