ACCELERATION | A vector quantity that represents the time-rate of change in velocity of an object. a= ∆v/t |
ACCELERATION DUE TO GRAVITY | Symbol g. Same for all objects regardless of their mass |
THE MAGNITUDE OF g NEAR THE SURFACE OF THE EARTH | 9.8 M/s2 |
CENTRIPETAL ACCELERATION | The acceleration experienced by an object traveling in uniform circular motion |
CENTRIPETAL ACCELERATION IS DIRECTED | toward the center of its curved path |
CENTRIPETAL ACCELERATION FORMULA | αc= v2/r |
CENTRIPETAL FORCE | The force that causes centripetal acceleration. |
CENTRIPETAL FORCE FORMULA | Fc = mac = mv2/r |
THE CENTRIPETAL FORCE IS THE NET FORCE ACTING ON THE OBJECT | This maintains its constant speed because there are no tangential forces acting up it. |
CENTRIPETAL FORCE IS DIRECTED TOWARD | the center of the path of an object undergoing uniform circular motion. |
