In this lesson summary review and remind yourself of the key terms and calculations used in measuring unemployment, the labor force, the unemployment rate, the labor force participation rate, and the natural rate of unemployment. Topics...

In this activity, learners will use different materials to find the most effective way to use an inclined plane (in other words, moving an object with as little force as possible). This is a guided inquiry. Although the students will be...

In this culminating activity of the unit which highlights how forces play a role in engineering design and material choices, students explore and apply their knowledge of forces, friction, acceleration, and gravity in a two-part experiment.

Young scholars create a parachute to explore how air pushes up against an object and slows it down as it falls.

This site is on the science and art of skateboard design, including equipment, tricks, glossary of terms, and a live webcast of a skateboard performance.

Do you need to review any of Newton's three laws? This website contains a video collection on Newton's Law from a physics course at East Los Angeles College. In twelve lectures, each law is explained with examples. Also discussed is...

A detailed look at the aerodynamic principles associated with cycling. Good science and even better web page design. Includes an online calculator that allows the user to calculate the aerodynamic drag and propulsive power of a bicyclist...

A webpage with equations and examples of how to solve inclined planes problems. Learn how to deal with slopes when surfaces usually aren't perfectly horizontal.

Animation of the single-block "Earthquake Machine" model shows how "Forces, Faults, and Friction" interact. [0:16]

Students must determine the force of friction on a car on a turn and the maximum speed the car could navigate a turn.

Watch how the placement of two weights attached to a chain on different sides of a pulley affect the movement of the system. You can adjust the heaviness of the weights.

Provides a long list of physics formulas for easy reference.

This resource provides a brief overview of friction. Its' affects on solids, liquids and gases is described with diagrams. An explanation of how friction is measured is included in the discussion. An online quiz can be used to check your...

This study guide on Newton's Laws covers key terms, the three laws, free body diagrams, friction coefficients and tension. Includes equations and an example problem with solution. It is available for download with free registration.

Students work in teams to investigate how aerospace engineering relates to sports, especially golf ball design and the physics of bounce. They use this information to determine whether these aerospace principles can be applied to...

Here is a simulation demonstrating an object placed on an inclined plane. The user will vary the slope of the plane to see the relationship the slope has on the gravity of the object and the static friction.

A handy resource that gives an overview of equations and definitions pertinent to an introductory, college-level physics course, with two of its three sections focusing on motion-related topics and principles.

Science experiment in which you make a hovercraft, a machine that uses compressed air to do work, from a paper cup. Includes full list of materials, procedures, and scientific explanation of how air flow can minimize friction and cause...

Students will create a gravity ball launcher to demonstrate their understanding of mass, force, momentum, and motion. The students will use critical thinking, measurement, and observation and analysis of data to make changes and improve...

A short biography about Charles Coulomb, known for developing Coulomb's law, the definition of the electrostatic force of attraction and repulsion.

This lesson is for 9th grade physical science students. It begins with an inquiry-based lesson using a projectile motion computer simulation. It culminates with students building a catapult; applying and connecting science knowledge from...

Students will drop and shoot horizontally "Nerf" balls from a variety of known heights then record the amount of time it takes for the ball to hit the ground for each trial. They will plot height vs. time data and create a trend line for...

An easy to do activity that investigates the basic theories of inertia. The activity is in lesson plan format that meets NSES standards.

This lesson focuses on electric charges. Electric current is the flow of electric charge. Some insulating materials become electrically charged when they are rubbed together. A substance that gains electrons becomes negatively charged,...
