Concept Summary
... o Acceleration changes the velocity (in magnitude, direction, or both). o Acceleration can speed you up or slow you down (often called deceleration). o Constant velocity means the acceleration is zero and visa versa. o Average acceleration = change in velocity/elapsed time vector quantity = magnit ...

The Force
... In the equation for weight, g is no longer considered the acceleration due to gravity, but rather the gravitational field strength, with units of newtons/kilogram. Inertial and gravitational masses have been tested and are believed to always be equal in amount. This is why all objects freefall at th ...
