8.2: Physics 3 Dimensions & Progressions

Unit 1

● I can defne mass, speed and kinetic and potential energy. ● I can describe, develop a model, and graph the kinetic energy of two objects of different mass

● This is an interactive

● Ski Jump Interactive ● Ski Jump Student Worksheet

where the students can alter the mass, the form and then measure the height of the skier’s jump. As the skier goes down the track, there is a graph that tracks the conservation of energy. Recommend building a study guide.

Activity: Potential & Kinetic Energy Lab

Objective

Overview

Materials

● I can defne mass, speed and kinetic and potential energy. ● I can describe, develop a model, and graph the kinetic energy of two objects of different mass

● Students defne the terms “potential energy” and “kinetic energy,” and explain the difference between the two. They observe potential and kinetic energy of various sized marbles. They discover that the heavier and larger an object is, the more potential energy it has. ● Link includes lab write up sheet.

● Potential and Kinetic Energy ● 3 different sized marbles, Wood for a ramp, Meter stick, Milk carton, Rubber bands (one for each student)
