This resource presents the text of one of Aristotle's "Physics can be read online or downloaded by individual chapters in MP3 or PDF format. In addition, each chapter has downloadable support material which focuses on various reading...

This is an interactive inquiry where students will investigate the speed of an object and the energy it exerts as it crashes into other objects. Students will understand that the more speed an object has, the more energy it has in a...

[Free Registration/Login Required] Create a science test that checks for student understanding in science, for common misconceptions, as well as for correct ideas. This is a list of key ideas related to Energy: Forms, Transformation,...

[Free Registration/Login may be required to access all resource tools.] Understand how to evaluate data presented in graphs based on speed and velocity calculations.

This essay from the NOVA Web site explores the impact Einstein made on physics and most everything we know about the cosmos.

Salt crystals demonstrate how forces can be directed in mechanical systems.

In this activity, students' will record the x- and y-coordinates of a rod moving in a figure-eight pattern. They will then use the recorded motion information to separately model the x- and y-motion as a function of time. They will plot...

Centripetal motion can be a complex topic so use this website to review the key concepts, equations, and skills for centripetal motion. Also, the connection to centripetal acceleration is discussed here.

In this activity, students create a situation that produces linear behavior by stepping heel to toe and taking distance readings as each step is taken. Students then apply the properties of a linear function to develop a model for motion.

Students physically provide motion data that is collected by a CBL and then graph the data. They determine if they "moved in the right directions" by comparing their graph with those printed in the activity.

Learners will use Vernier motion detector and Logger Pro software to first discover if air resistance of an industrial size coffee filter is a vtm or vt2m relationship (vt = terminal velocity). Once this relationship is found it will be...

American inventor Lee De Forest was a pioneer of radio and motion pictures. He received more than 300 patents over the course of his lifetime, the most important of which was for a three-electrode vacuum tube, or triode, that he called...

Determine the difference in pressure that leads to the motion of masses in an hydraulic lift and the difference in height when the piston reaches equilibrium.

This lesson focuses on developing a way to cross all 7 Bridges of Konigsberg without crossing any of them more than once. Euler discovered it was impossible, but he developed the idea of using graph theory to determine if it would be...

Did you know the continents on Earth are in constant motion? Our knowledge of this is thanks to both Alfred Wegener and Harry Hess. This article discusses the work of these two scientists.

Students act as astronomers, studying stars in a patch of sky in our own galaxy. Using simulated data from spectroscopy and other real-world instrumentation, students learn to determine star positions, radial velocity, proper motion, and...

Many sports use a ball in some way or another. We throw them, dribble them, hit them, kick them, and they always bounce back. What makes a ball so bouncy? In this experiment you can investigate the effect of air pressure on ball bouncing.

Are you a piano player or a video gamer? Then you might have a quick reaction time that can come in handy while playing sports. Find out how to measure your reaction time and compare it to your friends and family with this fun experiment.

This well-written explanation of relativity includes animations and pictures which may be helpful in understanding a tough topic.

The greater the force applied to an object, the greater the change in speed or direction of the object.

First one to empty the jug wins! And it's not as easy as it sounds...

Information about the interference of sound and its causes. Well-illustrated and good explanations of the concepts; part of a large hyper-textbook on various physics concepts.

Here's an abstract of a project from Science Buddies that asks you to experiment with bicycle gears and the circumference of the wheel to determine revolutions per minute.

Through an animated illustration of a dot diagram and time graphs, students learn about constant positive velocity.
