Graphing Speed and Mass versus Kinetic Energy: Sports

This sports-themed energy worksheet hits a HOME RUN to support the standard MS-PS3-1! Graphing speed and mass versus kinetic energy is an effective way to help kids see the relationship between these variables. In this middle school activity, students:
  • Calculate kinetic energy
  • Graph mass versus kinetic energy
  • Graph speed versus kinetic energy
  • Analyze their graphs for the relationship between mass and kinetic energy and between speed and kinetic energy
The activity gives and uses the equation for KE, but it is easy math (plugging in numbers, if you will). This is not high school physics and is totally appropriate for middle school science.
 
In Part One, students calculate and graph the kinetic energy of various sports balls (different masses) that are traveling at a constant speed.

In Part Two, students calculate and graph the kinetic energy of a baseball (constant mass) thrown at different speeds.
