Kinematic equations help solve for an unknown in a problem when an object has either a constant velocity or constant acceleration. This video will help you choose which kinematic equations you should use, given the type of problem you're working through.

These reading guides for OpenStax College Physics cover the chapters most often taught in the first semester. They are organized by chapter and section. The guides include chapter summaries, core terminology and equations, and review questions.

Investigate collisions on an air hockey table. Set up your own experiments: vary the number of discs, masses and initial conditions. Is momentum conserved? Is kinetic energy conserved? Vary the elasticity and see what happens.

Definition of period and frequency for an object moving in a circle. Connecting period and frequency to the magnitude of the angular velocity.

Students learn about the physical force of linear momentum movement in a straight line by investigating collisions. They learn an equation that engineers use to describe momentum. Students also investigate the psychological phenomenon of momentum; they see how the "big mo" of the bandwagon effect contributes to the development of fads and manias, and how modern technology and mass media accelerate and intensify the effect.

Students are asked how acceleration, mass, momentum and velocity are involved in mountain boarding. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.

This activity is an inquiry lab where students are challenged to create a slow moving and fast moving plane and measure the speed.

This activity is an outdoor lab where students gather data and calculate velocity, acceleration, momentum, and force of a vessel they create to safely deliver 2 eggs from the roof to the pavement below.

In this activity, students will learn about and apply the Laws of Physics to successfully launch and land a raw egg. The activity frames the problem around designing and building a bottle rocket that will protect a raw egg being launched into the air at least seven meters. Resources included in this lesson are found at the bottom of this document and include:

-Teacher guide
-Physics note sheets on motion, speed, velocity, acceleration, momentum, force, friction, Newton’s Laws of Motion, potential and kinetic energy and gravity.
-Egg Launch Instructions
-Link to Bottle Rocket Launching Instructions
-Links to videos
-Post Assessment

This subject provides an introduction to fluid mechanics. Students are introduced to and become familiar with all relevant physical properties and fundamental laws governing the behavior of fluids and learn how to solve a variety of problems of interest to civil and environmental engineers. While there is a chance to put skills from calculus and differential equations to use in this subject, the emphasis is on physical understanding of why a fluid behaves the way it does. The aim is to make the students think as a fluid. In addition to relating a working knowledge of fluid mechanics, the subject prepares students for higher-level subjects in fluid dynamics.

Under the "The Science Behind Harry Potter" theme, a succession of diverse complex scientific topics are presented to students through direct immersive interaction. Student interest is piqued by the incorporation of popular culture into the classroom via a series of interactive, hands-on Harry Potter/movie-themed lessons and activities. They learn about the basics of acid/base chemistry (invisible ink), genetics and trait prediction (parseltongue trait in families), and force and projectile motion (motion of the thrown remembrall). In each lesson and activity, students are also made aware of the engineering connections to these fields of scientific study.

Students conduct an experiment to study the acceleration of a mobile Android device. During the experiment, they run an application created with MIT's App Inventor that monitors linear acceleration in one-dimension. Students use an acceleration vs. time equation to construct an approximate velocity vs. time graph. Students will understand the relationship between the object's mass and acceleration and how that relates to the force applied to the object, which is Newton's second law of motion.

All of us have felt sick at some point in our lives. Many times, we find ourselves asking, "What is the quickest way that I can start to feel better?" During this two-lesson unit, students study that question and determine which form of medicine delivery (pill, liquid, injection/shot) offers the fastest relief. This challenge question serves as a real-world context for learning all about flow rates. Students study how long various prescription methods take to introduce chemicals into our blood streams, as well as use flow rate to determine how increasing a person's heart rate can theoretically make medicines work more quickly. Students are introduced to engineering devices that simulate what occurs during the distribution of antibiotic cells in the body.
