A video and a short quiz on acceleration.

Use your knowledge about friction to help Carrie get to the Invigatron before someone steals it. Following the activity, read more about friction and resistance, and then take a quick quiz to check for understanding.

Students learn about various forces and how they relate to everyday life in this interactive learning module.

Covers the meanings of force, friction, and gravity, and the differences between magnetic and elastic spring force, and between weight and mass. The effect of air resistance on an object's motion is also touched upon.

This resource provides reproducibles that aide in student learning of force and motion. Also offers hands-on and cooperative learning activity ideas as well as an ESL/ELD activity. This resource is in PDF form; requires Adobe Reader.

A lesson about friction can be found on this website. Students will experiment to see how motion and frictional force affect the game of football.

Learn about the force of friction on this reference page which defines why friction is important and how it can change physic problems.

Step into Dirtmeister's Science Lab and become a Science Snooper! Work side by side with him as he sets out to answer the challenge question: "How does the force of friction affect us in our daily lives?"

A simple demonstration using a person on a bicycle to illustrate how thrust and resistance balance to achieve a constant rate of speed.

The Thinking Fountain provides this simple experiment for understanding friction and it relationship to energy.

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.

Review the key concepts, equations, and skills for friction, including how to find the direction and magnitude of the friction force.

This is part of a lesson on Newton's Laws of Motion that focuses on inertia and mass. It restates Newton's first law of motion. The lesson also gives a helpful visual description concerning friction.

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.

Learners 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...

Kids learn about the science behind friction including how it works as a force to slow things down, how it helps us stand, preventing friction, types, and fun facts.

This simulation of a pendulum will demonstrate how friction and force have to change to keep the mass in the same position on the pivoted rod.

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...

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 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.

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