From high school geography class, you may remember that "air tends to flow from high pressure to low pressure". To understand why this happens, it is key to realizing that gasses (but also liquids) exert a force on their surroundings...

[Free Registration/Login may be required to access all resource tools.] How to calculate acceleration from force and mass, and force from mass and acceleration.

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]

The Illinois Institute of Technology provides a lab activity on precession and spinning tops. Designed for primary grades, but easily adapted for any level. Includes directions and assessment ideas.

The mathematics associated with gyroscopes can be investigated through this interactive page. Users enter critical parameters about gyroscopes and rotational motion descriptors are given.

Students must determine the force of friction on a car on a turn and the maximum speed the car could navigate a turn.

Help your students explore how the motion of objects changes during a collision. This website includes work samples, phenomena, assessment templates, and videos that focus on collision design solution.

In this guided inquiry demonstration, a person on rollerblades and a medicine ball are used to teach the concept of conservation of momentum. Various sorts of collisions are used to show how momentum is conserved within a system.

[Free Registration/Login Required] Simulate the launch of a rocket to see how rocket propulsion works. After the activity, answer a challenge question to check for understanding.

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...

Students explore different situations where two side-by-side carts on a low-friction track push away from each other and travel in opposite directions. The goal is to investigate the effects on the relative mass.

A virtual collision track with colliding or exploding carts allows students to explore elastic and inelastic collisions. They can vary the mass of the two carts and their pre-collision velocities. An accompanying activity sheet which...

Students demonstrate the properties of inertia with some common kitchen materials.

In this rocket experiment, middle schoolers will investigate the question, "Which amount of water will cause the rocket to stay in the air the longest?" Students will compare how long the rocket was in the air with how much water was in...

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.

Students will understand that pushes and pulls can have different strengths and directions. Students investigate the effects of these different pushes and pulls.

Assess your understanding of force, mass and acceleration and the relationship amongst the three with this interactive multiple choice quiz. Immediate feedback is offered.

In this interactive tutorial, analyze two-body problems in which the objects are moving in different directions.

Introduce students to the ideas of motion and force in this hands-on lesson plan.

This digital textbook covers core physical science concepts and includes interactive features, real world examples, and videos.

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...

Video that uses an elevator in motion to describe the relationship among weight, gravity, and relative motion. [3:36] Includes a short quiz and a list of additional resources to explore.
