ZOOM cast members mix different amounts of baking soda and vinegar to see which combination produces the most carbon dioxide for launching a film-canister rocket. [3:23]

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."

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.

Students must calculate the distance an object will move up an incline using Newton's Laws. Mass, angle, gravitational field, coefficient of friction and initial speed will be generated randomly.

Students must calculate the speed of a block when it returns to its original location on an incline using Newton's Laws. Mass, angle, gravitational field, coefficient of friction and initial speed will be generated randomly.

Try to find the sweet spot for hitting a baseball so that it travels the greatest horizontal distance.

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.

[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...

By the end of this section, you will be able to define net force, external force, and system; understand Newton's second law of motion; and apply Newton's second law to determine the weight of an object.

[Free Registration/Login may be required to access all resource tools.] Describes friction and how it opposes motion, and identifies types of friction.

Learners will create a gravity ball launcher to demonstrate their understanding of mass, force, momentum, and motion. The students will use critical thinking, measurement, and observation and analysis of data to make changes and improve...

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 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 will have an opportunity to determine what makes everyday objects move. Students will be given objects and asked to make predictions on how far each object will move after they blow on it. Then they will measure the distance and...

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...

A lesson about friction can be found on this website. Students will experiment to see how motion and frictional force affect the game of football.

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.

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.

Students gain first-hand experience on how friction affects motion. They build a hovercraft using air from a balloon to levitate a craft made from a compact disk (CD), learning that a bed of air under an object significantly reduces the...
