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...

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....

This Science Buddies project explains how to build a mechanism that will reproducibly swing a hammer so you can determine the amount of force needed to hammer a nail through various densities of wood. The Science Buddies project ideas...

Explore how friction between a surface and tires affects the movement of a bicycle.

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 program gives students a visual representation of the forces on a block that is on an inclined plane. The students can watch how force gravity, force normal, and force friction change as the angle of the plane changes. Students can...

This page summarizes each section of Chapter 5: Further Applications of Newton's Laws: Friction, Drag, and Elasticity from the AP Physics online text. These include friction, drag force, and elasticity: stress and strain.

Learners investigate forces and Newton's laws. Some topics examined are mass, friction, and Newton?s laws of motion. The resource includes example problems with solutions and a chapter quiz.

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...

[Free Registration/Login may be required to access all resource tools.] Understand the effects of magnitude of force pairs between objects. Know the differences between kinetic and static friction.

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...

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 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...

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 use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. The spring scale allows them to measure the frictional force that exists between the moving cup and the surface it slides on. By...

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

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

Learn why every force is a push or a pull.

This University of Oklahoma meteorology tutorial explores both high and low pressure systems--how they form and the different forms they take.

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

[Free Registration/Login may be required to access all resource tools.] Definition of force, how it relates to motion, and force as a vector.
