The kinetic energy of an object depends on its mass and speed. In this two-page physical science worksheet, students use real-world data to identify the relationships between kinetic energy, mass, and speed. Given a data table, students will observe how kinetic energy changes when one variable (mass or speed) changes. Then, using what they've learned, students will predict how kinetic energy will change when one variable is altered. After completing this worksheet, have learners try the Kinetic Energy, Mass, and Speed: Part 2 worksheet as a next step.
