... Are there forces in this motion? If so, what do they do? The force that causes the centripetal acceleration acts toward the center of the circular path and causes the change in the direction of the velocity vector. This force is called the centripetal force. ...

... used to think that a heavy object like a large stone falls faster than a light object like a coin. However, about 400 years ago an Italian named Galileo Galilei (1564 – 1642), measured the acceleration and speed of various falling objects. A famous story says that he dropped different objects from t ...

... In the absence of external forces, an object at rest remains at rest and an object in motion continues in motion with a constant velocity. What does this statement tell us? 1. When no force is exerted on an object, the acceleration of the object is 0. 2. Any isolated object, the object that do not i ...
