Learners learn the relationship between the electric and magnetic fields. Specifically, they verify that a magnetic field is created in a current carrying coil of wire and a changing magnetic field can induce a current in another coil of...

Wikipedia's site on centripetal force provides a section explaining the difference between centripetal force and centrifugal force. Includes formulas and hyperlinked terms.

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

In this activity, students investigate the effect that thrust has on rocket flight. Students will make two paper rockets that they can launch themselves by blowing through a straw. These "strawkets" will differ in diameter, such that...

[Free Registration/Login may be required to access all resource tools.] How to draw a velocity-time graph and what it represents.

[Free Registration/Login Required] Explore how angles affect the projectile motion of a thrown object. After the activity, answer a challenge question to check for understanding.

[Free Registration/Login may be required to access all resource tools.] The four types of friction and how they act on objects.

Students must predict the distance a box will move up an incline based on energy conservation. There will be friction present and some of the original KE will turn into heat.

Students must determine the power that is being exerted by a motor to pull a person up a frictionless incline.

Students must predict the distance traveled by a person on a sled. The person will start with potential energy due to gravity and then lose some energy on a hill. They will then lose the remaining energy on a level surface. You have to...

In this interactive physics tutorial, students will take a more qualitative approach to some collision problems. The questions provide a real test of conceptual understanding of momentum conservation in collisions.

As with collisions, this interactive physics tutorial shows students how momentum is conserved in explosions.

This lab was designed to have students practice the Atwood lab prior to doing it for real. Students can adjust the masses and the planet and then collect position vs. time data and velocity vs. time data.

Students must find out force normal on an object on an incline at the angle at which the object is first about to slip.

In this article the concept of vibrational motion and its relationship to waves is introduced.

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.

[Free Registration/Login Required] Use the interactive diagram to solve a projectile motion problem. After the activity, answer a challenge question to check for understanding.

[Free Registration/Login may be required to access all resource tools.] Featurea the definition of combining forces: Pulling down and pushing up, forces acting in opposite directions, forces acting in the same direction.

In this lesson plan we'll explore how we use fairly simple physics to draw particles which move according to the forces we feel in the real world (such as wind & gravity).

Review the key concepts and skills for inelastic collisions. Understand how to determine if a collision is elastic or inelastic.

Review how angular momentum is conserved if there is no external torque applied to a system. Specific scenarios are highlighted: system changing it rotational inertia, orbiting bodies, and rotational collisions.

A review page discussing how to break down forces into the horizontal and vertical components when force is at an angle.

Review the key concepts and skills for forces, including how to draw free body diagrams.

Review the key concepts, equations, and skills for friction, including how to find the direction and magnitude of the friction force.
