force and motion unit
... Have you ever wondered why and how objects begin to move and why objects stop all of a sudden? An object starts to move, stops moving, or changes directions ONLY when a force acts on it. Some forces act on objects directly and some forces act on objects indirectly. For example, when you push on a do ...

Circular Motion
... Satellites are fast-moving projectiles that continually fall, but never hit the ground The centripetal force that keeps them moving in orbit is GRAVITY. Important for weather, telecommunications, military, & GPS. Satellites don’t crash because they have sufficient tangential speed + no friction. ...
