[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.

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...

Young scholars create a parachute to explore how air pushes up against an object and slows it down as it falls.

Application of Newton's Law of force and gravity to computer graphic programming.

Experience the effect of friction, air resistance, and applied force upon a sledder. The speed, acceleration, and force values are displayed as the sled moves. Learners can vary the mass of the sledder and the size of the parachute...

A short biography about Charles Coulomb, known for developing Coulomb's law, the definition of the electrostatic force of attraction and repulsion.

An interactive tool where students can explore how a spring behaves, and how changing the elasticity, mass, push/pull force, and friction affect its motion or period. As the spring moves, its motion is shown on a distance-time graph.

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

Spanish-language site lets students discover the life and work of this physicist and engineer, who is known for his studies of electric charges.

This lesson introduces the concept of static friction and explains how it depends on the surface an object is resting on. It is 2 of 2 in the series titled "Static Friction Revisited."

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

This site is a discussion and animation about whether the total mechanical energy of a cart rolling down an incline is conserved, which can be determined if there are any external forces acting upon it.

Students must determine the work done by a horizontal force when there is no friction acting on the box. Students must then find the speed of the box after this work has been added to the box.

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.

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...

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.

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...

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

This University of Minnesota site provides a series of contextually rich problems pertaining to force, Newton's second law of motion, and linear kinematics.

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.

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

A detailed look at the aerodynamic principles associated with cycling. Good science and even better web page design. Includes an online calculator that allows the user to calculate the aerodynamic drag and propulsive power of a bicyclist...

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...
