... We define this inward acceleration as the CENTRIPETAL ACCELERATION. Centripetal means “CENTER SEEKING”. So for an object traveling in a counter-clockwise path. The velocity would be drawn TANGENT to the circle and the acceleration would be drawn TOWARDS the CENTER. To find the MAGNITUDES of each we ...

... Acceleration (the rate of change of velocity) is caused by a net force on an object. On Earth, one force we can always count on is the ever present force of gravity pulling down on any object that has mass. If gravity is the only force acting on an object, then we find the object will accelerate at ...
