When an object changes velocity, it accelerates. Acceleration is the change in velocity per second and is measured in m/s 2. Acceleration is a vector quantity because it has size and direction.

The role of whistler waves is certainly likely to be important, but the exact role in electron acceleration and loss by many other types of waves, and how the solar wind provides the source of ...

which also drives the type of acceleration model used. The model should correlate to its corresponding parameters, such as activation energy, stress level, etc. Once the test plan for the ALT has been ...

Various types of acceleration and deceleration are demonstrated, and examples are shown of how these types of motion may be applied in regard to gesture, gravity and perspective.
