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

By the end of this section, you will be able to discuss the general characteristics of friction, describe the various types of friction, and calculate the magnitudes of static and kinetic frictional forces.

We all recognize what friction is, but do you really understand what causes it? This project focuses on friction, its causes and forces and specifically how it affects how fast you can slip down slides.

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.

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...

[Free Registration/Login may be required to access all resource tools.] In this module, students learn what causes friction, what factors affect friction, and how it is calculated.

With this hands-on lesson, help learners understand force, gravity, friction, and speed. Students will also learn how each of these concepts affects the another.

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...

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.

See how forces affect various items that are pushed or pulled.

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."

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...

Use this simulation to see the results of applying a force to move an object. Analyze forces and friction using graphs.

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....

In the following interactive students will begin to calculate coefficient of friction on a car tire. They will also calculate ideal speed and angle of a car on a turn.

By the end of this section, you will be able to calculate coefficient of friction on a car tire and to calculate ideal speed and angle of a car on a turn.

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...

Forces are everywhere. Learn what they are, the characteristics of forces, different kinds of forces, and factors that affect them.

By the end of this section, you will be able to define nonconservative forces and explain how they affect mechanical energy, and to show how the principle of conservation of energy can be applied by treating the conservative forces in...
