A proof is a collection of statements in mathematics that explains how a conclusion is drawn from premises that are proven or believed to be valid. One of the most important purposes of mathematics is to show that the inference is a logical consequence of the premises, which is why proofs are so important.

Algebra, along with number theory, geometry, and analysis, is one of the broad areas of mathematics. Algebra, in its broadest sense, is the analysis of mathematical symbols and the rules for manipulating them; it runs through almost all of mathematics.

### Car traveling on a circular track

Cars A and B ride around a circular park with a radius of 20 miles in the diagram above. Both cars depart from the same starting point, as seen in the diagram. Car A travels at 60 miles per hour in a counterclockwise direction, while car B travels at 40 miles per hour in a clockwise direction. 20 minutes after car A, car B departs. Following the start of car A, how long does it take for the cars to meet? A. 63B. 75C. 83D. 126E. 188Congratulations on a right answer. Showcase Attachment with a Spoiler:

We looked at the fundamentals of circular motion in Motion in Two and Three Dimensions. Since it is shifting the direction of its velocity, an object in circular motion, such as one of the race cars seen at the beginning of this chapter, must be accelerating. The formula for this centrally controlled acceleration, known as centripetal acceleration, has been proven.

The rate at which an object rotates through a curve is measured in radians per second (rad/s). This acceleration is also known as a radial acceleration since it operates along the radius of the curved direction.

A force is required to produce acceleration. A centripetal or radial acceleration can be caused by any force or combination of forces. The stress in a tether ball’s cord, the force of Earth’s gravity on the Moon, friction between roller skates and a rink surface, the force of a banked roadway on a vehicle, and forces on the tube of a spinning centrifuge are just a few examples. A centripetal force is any net force that causes uniform circular motion. The direction of a centripetal force is the same as the direction of centripetal acceleration: toward the center of curvature. Newton’s second law of motion states that net force equals mass times acceleration: F textnet=ma. [latex] F textnet=ma.
