Momentum & Energy
In this segment we define the terms momentum and impulse. We see the impulse-momentum theorem in action by analyzing the motion of a freerunner and the motion of an egg hitting two very different surfaces.
The law of conservation of momentum is explained qualitatively and mathematically through examples involving billiards and roller skaters.
In this segment, we differentiate between elastic and inelastic collisions. The conservation of momentum and the conservation of energy are explored as we do examples involving these two types of collisions.
Work and energy are explored in this segment as we look at the work done by various types of forces. We also investigate what it means for the work done by an object when displacement and force are oriented in a variety of different ways.
Gravitational potential energy and kinetic energy are defined and explained mathematically through multiple example problems.
We explain the work-energy theorem and solve an example problem involving the equations for work and kinetic energy. We also discuss when work has a positive or negative value.
We investigate Hooke's Law as we explore the concept of spring potential energy. We also examine how to find this energy mathematically and graphically.
We explore the inner workings of a hydroelectric dam as we learn about the law of conservation of energy. The difference between conservative and non-conservative forces is illustrated and we work through an example problem involving gravitational potential energy and kinetic energy.
We learn how power relates to electrical and mechanical systems. We explore the multiple ways we can express power mathematically by working through an example problem that ties in Newton's second law and kinematic equations to find its solution.
Students analyze conceptual, mathematical, and physical models of atoms. This unit also includes an overview of protons, neutrons, and electrons, as well as a periodic table of elements.
We take our search for Georgia STEM careers to Carrollton with a visit to Southwire, the largest manufacturer of wire and cable in North America. Here we cover the types of careers available at Southwire. And we shine a (well-wired) spotlight on Southwire's Engineering Academy for high school students. Teachable Moments include descriptions of electricity and root cause analysis.
The focus of this unit is to help students understand the condition in which all competing influences counteract each other, resulting in a stable, balanced, or unchanging system.
