In this lesson 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).

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

Experience a simulation of ballistic trajectories in relationship to Earth's orbit. Java 1.5 or more recent is required.

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...

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

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 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 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...

[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 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.

The large scale horizontal flow of air in the atmosphere is driven by the imbalance of net radiation over the globe. This resource introduces us to the physical laws governing the horizontal motion of air. It also describes types of...

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

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.

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.

A Java-based simulation where students can observe what happens to a free-falling object, with and without air resistance. Controls allow the user to adjust settings and the results are graphed as the simulation progresses.

Through illustrated examples and interactive practice, students explore Newton's ability to relate the cause for heavenly motion (the orbit of the moon about the earth) to the cause for Earthly motion (the falling of an apple to the...

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

This simulation explores changing forces to move a heavy cart to exact positions.

An exceptional tutorial on the topic of vectors that offers many helpful graphics, some of which are interactive.

This article on weight will help you prepare for the AP Physics test. Included are example problems to help you practice.

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.

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.
