Gravity-centripetal acceleration
... Picture an object that has some velocity. What will happen to it if no forces act on it? Well, according to the first law, it will continue to move with a constant velocity. It will follow a straight-line path. • To make it change direction a force must act on it. In order to make it changes directi ...

Circular Motion and the Law of Gravity
... Rotational motion – the motion of an object that is spinning 1. The object spins about an axis. 2. The axis of rotation is the line about which the rotation occurs. 3. Circular motion is defined as a point on an object that moves (rotates) around an axis. Since the direction of the motion is constan ...

... Sometimes the speed of an object in circular motion is not constant (in other words, it’s not uniform circular motion). An acceleration component may be tangent to the path, aligned with the velocity. This is called tangential acceleration. It causes speeding up or slowing down. The centripetal acce ...
