Review the key concepts, equations, and skills for friction, including how to find the direction and magnitude of the friction force.

Through illustrated examples and interactive practice problems, students find the value of forces acting upon objects using force equations.

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 article on Khan Academy is about air and fluid resistance that is caused by friction.

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

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...

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."

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...

Explains what static and kinetic friction are and discusses the coefficient of friction for different situations. Presents two simple lab experiments and real-life examples of friction in action.

This is a glossary of terms and definitions used in Chapter 5: Further Applications of Newton's Laws: Friction, Drag, and Elasticity from the AP Physics online text.

Explore the world of finding individual forces. "The process of determining the value of the individual forces acting upon an object involve [sic] an application of Newton's Second law and an application of the meaning of the net force."

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.

In this lab, students will work on scientific inquiry skills: observation, developing questions, conducting an experiment, and collecting data. They will investigate forces using pop bottle rockets that they have designed.

Teaches what friction force is, the difference between static and kinetic friction, and how friction force is calculated.

Activity investigates the concept of how bicycle brakes use force and friction to stop or slow mechanical motion. Students work in teams to devise a simple braking system while suggesting improvements to current bicycle brake design.

Create an Atwood's machine and a modified Atwood's machine in this interactive. Change the amount of mass on either object, introduce friction forces, and measure distance and time in order to calculate the acceleration.

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.] Definition of friction, why it occurs, and the factors that affect it.

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...

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

Students must calculate the acceleration of an object down an incline when there is friction present. Mass, angle and coefficient of friction will be generated randomly.

In this Science-athon, students try to make their marble roll the farthest across a flat surface, using their knowledge of forces, motion, and energy to guide them through their apparatus design. Teachers must enroll online.
