1. Uniform circular motion is the motion of an object traveling at a constant speed on a circular path. Uniform Circular Motion

2. Let T be the time it takes for the object to travel once around the circle. Uniform Circular Motion

3. The wheel of a car has a radius of 0.29m and it being rotated at 830 revolutions per minute on a tire-balancing machine. Determine the speed at which the outer edge of the wheel is moving. A Tire Balancing Machine

4. Centripetal Acceleration An object tied to a string revolving in a circle under the influence of a constant inward tug. The object is continuously accelerated toward the center of the circle. If the string breaks the object flies off tangentially.

5. The direction of the centripetal acceleration is towards the center of the circle; in the same direction as the change in velocity. Centripetal Acceleration

6. The Law of Universal Gravitation Newton's Law of Universal Gravitation states that every object in the universe attracts every other object with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between the centers of the objects. Gravitational Constant, G = 6.67259* 10 -11 N. m 2 / kg 2
