This physics tutorial aims to model and predict not the motion of just one object, but rather what happens when two or more objects collide. The concept of momentum will be the main focus of this module.

This article helps students learn about Newton's laws of motion and the properties of force.

By the end of this section, you will be able to define normal and tension forces, apply Newton's laws of motion to solve problems involving a variety of forces, and use trigonometric identities to resolve weight into components.

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

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.

Online classroom site explaining the concept of balanced and unbalanced forces. The site has examples and exercises for the student to review and try.

In this interactive module, students use free-body diagrams, Newton's second law equation, and circular motion concepts to analyze a variety of physical situations involving the motion of objects in circles or along curved paths.

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

Through interactive illustrations and practice problems, students study Newton's Universal Law of Gravitation.

This study information helps students apply Newton's third law and understand forces.

This site is from the Physics Department at Georgia State University. The conservation of energy as a fundamental conservation law is presented and compared to other conservation laws (momentum and angular momentum). Links to further...

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.
