AAPT® is a strong professional physics science society dedicated to the pursuit of excellence in physical science education.

Winter and Summer National Meetings:
These National Meetings, held each winter and summer, are opportunities for members, colleagues, and future physicists from around the world to:

- participate in physics workshops
- meet and greet other physics educators
- form networks nationally and locally
- engage exhibitors and learn about the latest physics resources
- discuss innovations in teaching methods
- share the results of research about teaching and learning.

Dr. Sonwalkar is regarded as a leading expert in the application of computers in education. He has extensive research and development experience in hypermedia authoring, mobile learning, adaptive learning, and brain-based synaptic learning, advanced scientific visualization, database management systems, and computer simulation.

After receiving doctoral degree from MIT in the area of Molecular Dynamics of Nano-interfaces, he joined MIT as faculty in Mechanical Engineering, but his passion for technology enabled education led him become the founding director of Hypermedia Teaching Facility (Hypermedia Lab) at MIT and later he was appointed as the Principal Educational Architect of MIT.

Work, Energy, and Power Segment 5: Springs and Energy

Work, Energy, and Power Segment 6: Total Mechanical Energy

The force applied for on an object for a small duration causes change velocity of an object is studied under impact and impulse response. The change in velocity of an object is momentum. You will learn about impulse and momentum that leads to elastic and inelastic collisions.

Impulse and Momentum Segment 1: Center of Mass

Impulse and Momentum Segment 2: Impulse and Momentum

Impulse and Momentum Segment 3: Momentum and Force

Impulse and Momentum Segment 4: Elastic and Inelastic Collisions

Impulse and Momentum Segment 5: 1D Conservation of Momentum

Impulse and Momentum Segment 6: 2D Conservation of Momentum

In this topic, you will learn motion in a curved path and circle. And about force applied around an axis leading to torque (moment).
