Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time.

Explore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.

Students learn about the concept of pushing, as well as the relationship between force and mass. Students practice measurement skills using pan scales and rulers to make predictions about mass and distance. A LEGO MINDSTORMS NXT robot is...

Application of Newton's Law of force and gravity to computer graphic programming.

A video and a short quiz on acceleration.

In this investigation, students will learn that speed, velocity, and changes in velocity are the result of the action of forces on objects such as friction. They will be able to explain how the force of friction opposes motion by...

In the first of two lessons of this curricular unit, students are introduced to the concept of friction as a force that impedes motion when two surfaces are in contact. Student teams use spring scales to drag objects, such as a ceramic...

Students use LEGO MINDSTORMS robotics to help conceptualize and understand the force of friction. Specifically, they observe how different surfaces in contact result in different frictional forces. A LEGO robot is constructed to pull a...

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.

What causes wind? How does wind affect our weather? This website is neatly organized into topics about pressure, gradient force, Coriolis force, geostrophic wind, gradient wind, friction, boundary layer wind, and sea and land breezes....

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?"

This lesson will introduce forces and give an overview of some different types of forces.

An interactive playground for students to explore the physics of roller coasters. Learners investigate by changing the variables of force, velocity, friction, and vectors. Energy bar charts are displayed as the coaster car moves along...

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

A collection of experiments where students can learn about how friction works and affects the physical world. At the end, students design a tortoise to win by slowing it down using friction. Lesson includes explanation of the concept of...

You have probably heard the word "force" before in conversations. Here are a few examples: "the rocket had a lot of force at blast off" or "the force of the storm blew the roof off the building." What is force? Force is defined as a push...

This lesson will introduce the concept of friction and explain how it can affect forces. It is 4 of 5 in the series titled "Friction."

This University of Minnesota site provides a series of contextually rich, real-world problems demonstrating force and Newton's second law of motion.

In this lab activity, students will become familiar with Newton's 2nd Law of Motion. By investigating the motion of different skateboarders pulled with a variety of constant force values, they will discover that bodies acted on by a...

In this activity, students' will use a Dual range force sensor to measure the force required to pull a block across different surfaces. They will examine the results to see when more force is needed to move the block and understand the...
