C: Kinematics and Dynamics

This section contrasts motion of and around the center of mass of simple moving objects.

In this section are demonstrations of basic motion and trajectories of moving objects. This includes the vector nature of motion, and the acceleration of bodies in freefall.

Here you will see objects at rest remaining at rest, and objects in motion continuing in motion, until acted upon by an outside force.

F=ma, and all that follows. Here are demonstrations of the nature of acceleration and examples of forces acting on bodies in motion. This includes demonstrations of terminal velocity.

Action and reaction, forces in pairs: here are demonstrations of reaction forces and how they affect the motion of bodies.

This section includes demonstrations on the nature and effects of friction.

In this section you will find demonstrations of elastic and inelastic collisions, and the transfer of linear momentum and energy between bodies. It also includes examples of using collisions to measure velocity.

Here are demonstrations of mechanical energy and its conservation, its application in doing work, the differences between potential and kinetic energy, and the uses and nature of power.
