This lesson focuses on static electricity, including how particles can be charged by friction, and electrical forces and why they repel or attract each other. Includes a link to a test.

Newton's First Law also called the law of inertia is the most important thing to realize about motion. This article offers more information on motion and explains solved problems involving Newton's First Law. Also included is a video...

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...

Building upon their understanding of forces and Newton's laws of motion, students learn about the force of friction, specifically with respect to cars. They explore the friction between tires and the road to learn how it affects the...

Learn more about finding acceleration through the practices found in this lesson. "The process of determining the acceleration of an object demands that the mass and the net force are known." Check out this comprehensive site.

This site is an interactive app of an inclined plane showing the effect of the angle, the weight of the block, and the friction as a block is pulled up an incline.

Create an Atwood's machine and a modified Atwood's machine in this interactive. Change the amount of mass on either object, introduce friction forces, and measure distance and time in order to calculate the acceleration.

To learn how friction affects motion, students explore how different textures provide varying amounts of friction to objects moving across them. They build a tool to measure the amount of friction between a note card and various surfaces...

A clear explanation of Newton's First Law of Motion, the law of inertia, with diagrams and real-world examples. Useful for both students and teachers. Written by a high school physics teacher.

Students must calculate the acceleration of an object down an incline when there is friction present. Mass, angle and coefficient of friction will be generated randomly.

On the topic of energy related to motion, this summary lesson is intended to tie together the concepts of work, power, collisions, momentum and drag. A hands-on activity demonstrates this idea and reinforces students' math skills in...

Students must calculate the time it takes for a car to come to a rapid stop and the distance the car covers when stopping.

In this Science-athon, students try to make their marble roll the farthest across a flat surface, using their knowledge of forces, motion, and energy to guide them through their apparatus design. Teachers must enroll online.

Explore sports science and see how many points can you score with your bottle caps in Ruff's take on table hockey.

Students will have an opportunity to determine what makes everyday objects move. Students will be given objects and asked to make predictions on how far each object will move after they blow on it. Then they will measure the distance and...

Spanish-language site lets students discover the life and work of this physicist and engineer, who is known for his studies of electric charges.

This interesting and interactive exhibit demonstrates how Newton's Laws of Motion impact the design and safety of roller coasters.

In this lesson, young scholars make predictions about falling objects of different sizes and masses to learn about gravity and air resistance. Includes audio vocabulary list and extension activities.

[Free Registration/Login Required] In this unit children build on their existing knowledge of forces and learn that forces can be measured and compared. The unit focuses on 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.

For this activity, students 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.
