Oscillating is the process of swinging or moving to and fro in a steady, uninterrupted manner, and oscillating motion is the movement created by the process. An oscillating motion typically refers to a single step of the process in one direction then again as it swings to and from the opposite direction.Know More
Examples of oscillating motion are the swinging of a pendulum in a clock and the repetitive back-and-forth movement of a rotating fan.
Apart from the physical definition of the term, oscillating motion can also be applied to the mental process of fluctuating between ideas, opinions or convictions. Used in a sentence, this intent of the phrase is displayed when saying, "She oscillated between admiring him and being very angry with him for his actions." This implies that she is swinging back and forth between her emotions regarding the man's actions.
Oscillation is also used in the fields of mathematics and physics. In physics, it implies a repeated and regular fluctuation above and below a mean value. In mathematics, it typically refers to the differences in a function within a given interval, specifically between the least upper bound and the greatest lower bound. Another application of oscillation in mathematics is when determining the limit of the oscillating movement within an interval, also referred to as the "saltus."Learn more about Motion & Mechanics
Friction is a force that opposes motion, so it is unhelpful in all situations where the motion of an object is desired. A by-product of friction is that energy is wasted in the form of heat, which can cause problems in temperature-sensitive environments.Full Answer >
Retrograde motion was first described by Ptolemy as part of his solar system model. He described the motion of the planets in relation to the stars using the terms "retrograde" for westward motion and "prograde" for eastward motion.Full Answer >
A friction lab report is a lab report that describes the results of an experiment involving some aspect of friction, or the resistance of motion as two items move against one another. Lab reports contain detailed write-ups of the experiment and generally include an introductory, data, results and conclusion.Full Answer >
Friction is a resistive, physical-contact force that impedes motion. It occurs as a result of microscopically uneven surfaces, which are present even when the surfaces appear smooth to the human eye. If surfaces were perfectly smooth and in a vacuum, friction would not exist.Full Answer >
