[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will be asked to calculate the impulse applied to a physical system.

If you want to discover what makes rockets fly, this is an activity for you. You can even add different features, like fins, a nose cone, and a parachute to find out how these alter the flight!

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.

In this simulation, students pretend to launch bananas from a canon to the monkeys at the zoo. The monkeys sometimes let go of the branch at the exact moment the banana is launched. So the students must determine the correct aim angle...

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...

University site explaining what is meant by concurrent forces. The site has a free-body diagram with 3 forces acting on an arbitrary body. The site explains the conditions necessary for concurrency.

In this activity, students investigate why an egg does not break when thrown at a hanging sheet, but does when thrown at a wall. They will learn about momentum, and its applications.

A video and a short quiz on acceleration.

This online tutorial teaches students about the nature of the electric force. In this part of Lesson 1, two simple and fundamental statements will be made and explained about the nature of the electric force.

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...

[Free Registration/Login may be required to access all resource tools.] Explains inertia and how it affects motion, the relationship between inertia and mass, and how to overcome inertia.

The Coriolis force is a central element of the dynamics of ocean and atmosphere flows.

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.

The ideas of the Enlightenment began in Europe, but they were acted upon in the American colonies. See how the philosophies of John Locke and Rousseau influenced the thoughts and actions of Puritan clergy and political figures like...

[Free Registration/Login Required] An informational text about the science behind circus acts. A question sheet is available to help students build skills in reading comprehension.

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

Students must determine where a soccer ball will hit a wall based on the speed with which it is kicked. Students will also need to find the time in the air in milliseconds. This problem does not take place on Earth.

Cover standards for middle school force, mass, and the motion of an object with this site. Find work samples, phenomena, assessment templates, and videos that directly address standard.

[Free Registration/Login Required] Understand the concept of rotational inertia [moment of inertia) by analyzing the motion of a circus tightrope walker using this interactive simulation. A PDF worksheet and a video tutorial are also...

Learn what centripetal forces are and how to calculate them. Included are two problems with the solutions provided.

A handy resource that gives an overview of equations and definitions pertinent to an introductory, college-level physics course, with two of its three sections focusing on motion-related topics and principles.

Through illustrated examples and practice problems, students explore the centripetal force requirement. So for an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration.

Students discuss forces acting on objects in a trajectory motion. They review notes, study equations, solve projectile motion problems, and determine experimentally the impact point of a ball in projectile motion.

Students improve their understanding of momentum conservation and learn that a recoiling object in an elastic collision will transfer more impulse than if it collided inelastically.
