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.] Describes friction and how it opposes motion, and identifies types of friction.

In this hands-on activity - rolling a ball down an incline and having it collide into a cup - the concepts of mechanical energy, work and power, momentum, and friction are all demonstrated. During the activity, students take measurements...

In this document, we will try to answer a fundamental question of physical science, "Why do things start to move, slow down, speed up, stop moving or change direction?" In answering these core questions we can develop concepts that can...

Young scholars 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...

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...

With a simple demonstration activity, young scholars 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...

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.

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...

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....

Learn about forces (push or pull), gravity, and friction in this module by training dolphins.

Through ten lessons and numerous activities, students explore the natural universal rules engineers and physicists use to understand how things move and stay still. Together, these rules are called "mechanics." The study of mechanics is...

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

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...

A video and a short quiz on acceleration.

Students explore different situations where two side-by-side carts on a low-friction track push away from each other and travel in opposite directions. The goal is to investigate the effects on the relative mass.

This lesson will introduce the concept of friction and explain how it can affect forces. It is 2 of 5 in the series titled "Friction."

This lesson will introduce the concept of friction and explain how it can affect forces. It is 3 of 5 in the series titled "Friction."

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...

Learners observe objects in motion down a ramp to discover how the force of friction affects an object's motion. Includes the lesson plan, vocabulary list, and extensions for students.

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...

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 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.
