What is force? Illustrated discussion of how force is calculated and three familiar types.

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...

Students must determine the work done by a force on an angle when there is no friction present between the box and the table. Students must also find the final speed of the box after this work has been added to the box.

Students must determine the amount of work that is done by tension and the amount of work done by friction. Then students must find the work that turned into KE.

An animation that portrays the collision between a 3.0-kg loaded cart and a 2-kg dropped brick. It will be assumed that there are no net external forces acting upon the two objects involved in the collision. The only net force acting...

The animation portrays the collision between a 1.0-kg cart and a 2-kg dropped brick. It will be assumed that there are no net external forces acting upon the two objects involved in the collision. The only net force acting upon the two...

This lab was designed to have students look at the factors that might affect the angle at which an object will start to move when it is placed on an inclined plane. The friction coefficient of the surfaces, the strength of the...

The intricate relationship between work and mechanical energy is depicted in the animation for students to be able to visualize.

In this science project, you can investigate how submarines use stabilizing fins to move forward. Exploring friction and buoyant force you will get closer to understanding how these large ships function. Research resources are included...

A simple demonstration using a person on a bicycle to illustrate how thrust and resistance balance to achieve a constant rate of speed.

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.

This site from The Exploratorium Museum is a full description of a short activity. An electrophorus plate and a Leyden jar are made. The electrophorus is charged by induction. Its charge is transferred to the Leyden jar by conduction...

[Free Registration/Login Required] Use given friction formulas and an interactive diagram for an inclined plane to solve a motion problem. After the activity, answer a challenge question to check for understanding.

In this lesson summary review and remind yourself of the key terms and calculations used in measuring unemployment, the labor force, the unemployment rate, the labor force participation rate, and the natural rate of unemployment. Topics...

A detailed explanation of the different types of forces that can be applied to an object and how to represent them in a free body diagram. Includes examples and some practice problems to try, with solutions provided.

A collection of resources on how humans use machines and tools to meet their needs. Covers simple and complex machines, subsystems that transfer forces, mechanical advantage, speed ratio, the effect of friction, efficiency, the science...

Students learn first-hand the relationship between force, area and pressure. They use a force sensor built from a LEGO MINDSTORMS NXT kit to measure the force required to break through a paper napkin. An interchangeable top at the end of...

Experiment how torque causes an object to rotate. This interactive simulation shows how angular acceleration, moment of inertia, angular momentum, and torque relate to one another.

Learn how wheels and axles help with force and motion.

College-level online course highlighting the study of classical mechanics. This course focuses on Newtonian mechanics, fluid mechanics, and kinetic gas theory. Course features include a 35 video lecture series by Walter Lewin. Also link...

Within this resource, you will learn more about Newton's first law and real-world applications of this law.

Students use inclined planes as they recreate the difficult task of raising a monolith of rock to build a pyramid. They compare the push and pull of different-sized blocks up an inclined plane, determine the angle of inclination, and...

Student groups are provided with a generic car base on which to design a device/enclosure to protect an egg as it rolls down a ramp at increasing slopes. During this activity, student teams design, build and test their prototype...

Provides a long list of physics formulas for easy reference.
