While building and testing model rockets fueled by antacid tablets, students are introduced to the basic physics concepts on how rockets work. Students revise and improve their initial designs. Note: This activity is similar to the...

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

In this tutorial, examine the effect of forces acting at angles to the horizontal, such that the force has an influence in two dimensions- horizontally and vertically.

Students learn about the Newtonian mechanics principle of conservation of angular momentum and the application in the quantum mechanical world.

This presentation explains why a poorly defined system can lead to incorrect answers in physics problems.

A series of thought-intensive, multichoice questions concerning pendulums and provided for by the University of Maryland. A downloadable software program on pendulums is also included.

Students explore angular momentum and conservation. Some topics examined in the activities are angular momentum, torque, and conservation. The resource consists of video clips, lecture notes, practice problems, and exam questions....

From a chapter on Linear Momentum and Collisions in a Physics textbook. This section of the chapter covers linear momentum, how momentum and force are related, how momentum fits into Newton's second law of motion, and how to calculate...

[Free Registration/Login may be required to access all resource tools.] Students will identify how work and force are figured out on inclined planes as well as how to apply Newton's Second Law of Motion to them.

An exceptional tutorial on the topic of vectors that offers many helpful graphics, some of which are interactive.

The purpose of this activity is to demonstrate Newton's 3rd Law of Motion, which is the physical law that governs thrust in aircraft. The students will do several activities that show that for every action there is an equal and opposite...

This site, in German, offers numerous apps that illustrate common physics principles. Apps are organized into categories: mechanics, oscillations and waves, electrodynamics, optics, thermodynamics, the theory of relativity, physics of...

If every action has an equal and opposite reaction, what kind of physical action would it take for the earth to notice us? Check out Vsauce's video on what would happen if everyone on Earth got together and jumped. [7:13]

Students explore the relative mass of two colliding objects, and determine if that can be used to quickly predict the post-collision speed of the objects? An activity sheet guides learners through the process of determining the rule for...
