Students analyze a collision between a moving cart and a dropped brick that lands on top of it. They use position-time data to determine the pre- and post-collision speeds of the cart and the brick. The individual momentum values of the...

Wikipedia provides an encyclopedia definition of a rocket, including information on rocket history, size, types, and more.

In this activity, students will design and construct a water bottle rocket. Students will demonstrate understanding of a good experimental design and analysis of results.

Online classroom site explaining the concept of balanced and unbalanced forces. The site has examples and exercises for the student to review and try.

In this activity, students move in a specific way in front of the motion detector to create motion plots that match a given Distance versus Time plot. They make connections between types of movements and characteristics of Distance-Time...

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....

Students' use a motion detector to examine how different types of motion affect the shape of the distance versus time plot. They explore how changes in direction and other factors affect the shape of the plot.

Variation on the standard Atwood's Machine model, where one hanging mass swings like a pendulum and the other remains stationary. Manipulate the conditions and observe the results.

[Free Registration/Login may be required to access all resource tools.] In this online lesson students will learn about Torque and how to calculate Torque in various situations.

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...

An introduction to our solar system: the planets, our Sun and our Moon. Students begin by learning the history and engineering of space travel. They make simple rockets to acquire a basic understanding Newton's third law of motion. They...

In this interactive module, students use free-body diagrams, Newton's second law equation, and circular motion concepts to analyze a variety of physical situations involving the motion of objects in circles or along curved paths.

Swing virtual pendulums and compare the motion of one oscillating weight on a horizontal spring to a second weight on another spring. Then, compare how these motions differ from the motion of a simple pendulum.

A video and a short multiple-choice quiz on the meaning of inertia.

Do you know how gravity affects you? This module defines gravity and explains how gravity affects the motion of objects.

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...

In this activity, students construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas - produced from a chemical reaction between an antacid...

Through examples and practice problems, this interactive tutorial helps students understand forces that are in a state of equilibrium with a net force of zero.

By using different materials students construct a parachute to show how air resistance slows down its fall in this lesson.

Middle schoolers build a device to protect an egg and prevent it from breaking when dropped.

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...

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

A series of graphics, downloadable animations and text describe and explain the motion of a pendulum. Some sections require an understanding of calculus.

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.
