Students simulate block and tackles to lift heavy objects. They lift cargo by hand with the whip and the two-fold purchase to simujlate what crew members do aboard ships. They measure the effort and distance pulled for a gun tackle, luff...

In this health worksheet, learners find the words that are found in the puzzle related to burns and the answers are found at the bottom of the page.

In this literacy worksheet, students look for the words that are related to the theme of the worksheet. They also work on the skills of spelling and word recognition.

Students explore animal diets and teeth. In this animal science lesson, students view photos of animals and their teeth. Students identify the type of diet the animal has based on the teeth. Students are introduced to the terms...

Students use video cameras as a way to analyze and understand motion.  In this motion lesson students complete an activity that helps them better understand motion  and calculate time.

Students complete several worksheets about machines.  In this machine lesson students complete several handouts that describe the different machines  and how pulleys work. 

Students study harmonic motion and its oscillation.  In this simple harmonic motion lesson students demonstrate a series of regular oscillations and explain the theory behind the experiment. 

Students explain how wind direction affects sail angle. In this physics lesson, students measure the speed of the yacht while varying different factors. They summarize and share their finding to class.

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.

In the following interactive students will begin to discuss the general characteristics of friction and describe the various types of it. They will also calculate the magnitude of static and kinetic friction.

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...

An interactive simulation that teaches about friction, thermodynamics, and heat by making observations while rubbing two objects together. This simulation can either be downloaded or played online and includes handouts, lesson plans, and...

Learn how friction causes a material to heat up and melt. What happens on an atomic level when you rub two objects together?

With a simple demonstration activity, students are introduced to the concept of friction as a force that impedes motion when two surfaces are in contact. Then, in the Associated Activity (Sliding and Stuttering), they work in teams to...

Explains what static and kinetic friction are, what their coefficients of friction are in different scenarios, and how these concepts are applied when looking at automobile braking distances and vehicle control when driving.

Students are introduced to the concept of inertia and its application to a world without the force of friction acting on moving objects. When an object is in motion, friction tends to be the force that acts on this object to slow it down...

This is a list of 43 problems/exercises that cover the content of Chapter 5: Further Applications of Newton's Laws: Friction, Drag, and Elasticity from the AP Physics online text.

[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.

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.

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

[Free Registration/Login may be required to access all resource tools.] The four types of friction and how they act on objects.
