The Mystery of Motion: Momentum, Kinetic Energy and Their Conversion

In this video lesson, the concept of momentum applied to hard-body collisions is explained using a number of simple demonstrations, all of which can be repeated in the classroom. Understanding Newton's Laws is fundamental to all of physics, and this lesson introduces the vital concepts of momentum and energy, and their conservation. Only some preliminary ideas of algebra are used here, and all the concepts presented can be found in any high-school level physics book. In terms of materials required, getting hold of large steel balls may not be easy, but large ball bearings can be procured easily. On the basis of what students have learned in the video, teachers can easily generate a large number of questions that relate to one's daily experiences, or which pose new challenges: for example, in a collision between a heavy and light vehicle, why do those inside the heavier one suffer less injury?

It's interesting and great. Using blackboard might be better than white paper for displaying those formulas.

Thank you, nice

Lecture was good but too many breaks in such short time!

KE is inversely proportional to M when momentum is constant .
Therefore motorcycle will have more KE than truck.

There is no kinetic energy in a moving mass there is force Mv squared kinetic energy is the energy of consistent work from a consistent force regards Graham Flowers
