Momentum & Energy

Start Unit

9 Segments in this Unit

Segment 4A: Momentum and Impulse
We define the terms momentum and impulse.

Segment A: Momentum and Impulse

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.

Segment 4B: Conservation of Momentum
We explain it qualitatively and mathematically.

Segment B: Conservation of Momentum

The law of conservation of momentum is explained qualitatively and mathematically through examples involving billiards and roller skaters.

Segment 4C: Collisions 
We differentiate between elastic and inelastic collisions

Segment C: Collisions

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.

Segment 4D: Work 
We look at the work done by various types of forces

Segment D: Work

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.

We define and explain mathematically through multiple example problems.

Segment E: Kinetic Energy and Gravitational Potential Energy

Gravitational potential energy and kinetic energy are defined and explained mathematically through multiple example problems.

Segment 4F:  Work-Energy Theorem 
Learn work-energy theorem and solve example problems.

Segment F: Work-Energy Theorem

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 and explore the concept of spring potential energy.

Segment G: Spring Potential Energy

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.

 

Segment 4H: Conservation of Energy 
We explore the inner workings of a hydroelectric dam.

Segment H: Conservation of Energy

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.

 

Segment 4i: Power
We learn how power relates to electrical and mechanical systems.

Segment I: Power

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.

Unit 7: Solutions, Acids, and Bases

Students discover how solvents dissolve ionic and covalent solutes and learn how to measure solution concentration by mass percent, molarity, and molality. This unit also covers colligative properties.

The Coca-Cola Company

If you’ve got an idea for the next great flavor of Coca-Cola but don’t know what to do with it, we’ve got you covered. We visit the world headquarters of The Coca-Cola Company in downtown Atlanta and talk with a few of their nearly 100,000 employees about what it takes to be one of the most recognized brands on the planet. As it turns out, those high school chemistry classes might come in handy.

Our host recaps the content in unit 1, " Science and Engineering Practices."
