Cosmic Ray Momentum

What happens when two worlds collide? In the first of several activities, future physicists experiment with colliding ball bearings or Newton's cradle. Another activity requires the use of an air track with cars to examine collision....

A suggested sequence of events lays out five hands-on activities and four creative assessments on the conservation of momentum. Using spring scales and mail scales, junior physicists examine Newton's Third Law. After you have taught the...

What happens to the momentum of an object when it strikes another object? Scholars roll a marble down a ramp so it collides with another marble. By measuring the speed of each marble before and after the collision, pupils answer this...

Explanations for six different physics lab activities and five suggested assessments are contained in this resource by the National Science Teachers Association. Any combination can be used to open learners' eyes to rotational motion....

Planning a physics unit on energy can take a lot of work, luckily this instructional presentation is here to help. Covering everything from work and energy to elastic collisions and the conservation of momentum, this comprehensive...

By the end of this section, you will be able to describe the law of conservation of linear momentum, derive an expression for the conservation of momentum, explain conservation of momentum with examples, and explain the law of...

Students explore angular momentum and conservation. Some topics examined in the activities are angular momentum, torque, and conservation. The resource consists of video clips, lecture notes, practice problems, and exam questions....

If your head is spinning when you consider teaching the action of spinning, this video is sure to settle things. First, the motion is defined and described. The conservation of angular momentum, the Coriolis effect, and the air pressure...

Be impulsive with your high school physics class. Emerging physicists review the slide presentation and learn about impulse, momentum, collisions, and how each variable may be affected. They complete practice problems and conclude with a...

Rolling for momentum. As part of a study of mechanical energy, momentum, and friction, class members experiment rolling a ball down an incline and having it collide with a cup. Groups take multiple measurements and perform...
