They oscillate back and forth about a fixed position. A simple pendulum and a mass on a spring are classic examples of such vibrating motion. Though not evident by simple observation, the use of motion detectors reveals that the vibrations of these objects have a sinusoidal nature. There is a subtle wave-like behavior associated with the manner in which the position and the velocity vary with respect to time. In the next lesson, we will investigate waves.
As we will soon find out, if a mass on a spring is a wiggle in time , then a wave is a collection of wigglers spread through space. As we begin our study of waves in Lesson 2, concepts of frequency, wavelength and amplitude will remain important.
A force of 16 N is required to stretch a spring a distance of 40 cm from its rest position. What force in Newtons is required to stretch the same spring …. Ut tensio, sic vis. As the extension, so the force. Force and stretch are proportional to one another such that if you double the force, the amount of stretch will double. If you triple the force, the amount of stretch will triple. If you half the force, the amount of stretch will halve.
So the answers here are:. Perpetually disturbed by the habit of the backyard squirrels to raid his bird feeders, Mr. H decides to use a little physics for better living. His current plot involves equipping his bird feeder with a spring system that stretches and oscillates when the mass of a squirrel lands on the feeder. He wishes to have the highest amplitude of vibration that is possible.
Should he use a spring with a large spring constant or a small spring constant? H should use a spring with a low spring constant k. If this ratio is low, then there will be a relatively large displacement for any given F value. Being displaced furthest from the equilibrium position will set the spring into a relatively high amplitude vibrational motion. Referring to the previous question.
If Mr. H wishes to have his bird feeder and attached squirrel vibrate with the highest possible frequency, should he use a spring with a large spring constant or a small spring constant? H should use a spring with a large spring constant k. Using a large spring constant k will cause the period to be small. A small period corresponds to a high frequency.
Get them squirrels, Mr. Answer: Energy is conserved. Which of the following mass-spring systems will have the highest frequency of vibration? Frequency and period are inversely related.
The highest frequency will have the shortest smallest period. Both springs have the same mass; only the spring constant k is different. A spring with a higher spring constant will have a shorter period. This is consistent with the equation for period. Both springs have the same spring constant; only the suspended mass m is different.
A spring with a smaller suspended mass will have a shorter period. Physics Tutorial. My Cart Subscription Selection. Student Extras. We Would Like to Suggest Why just read about it and when you could be interacting with it?
Interact - that's exactly what you do when you use one of The Physics Classroom's Interactives. We would like to suggest that you combine the reading of this page with the use of our M ass on a Spring Interactive. You can find it in the Physics Interactives section of our website.
The M ass on a Spring Interactive provides the learner with a simple environment for exploring the effect of mass, spring constant and duration of motion upon the period and amplitude of a vertically-vibrating mass.
Visit: M ass on a Spring Interactive. See Answer Answer: Ut tensio, sic vis. So the answers here are: a. But how we wait and wait and wait for spring, charting every sign that it is arriving. It may be the only time of year we treasure our brave little weeds like coltsfoot and dandelion. But yes, waiting for Spring is like waiting for your birthday when you are a kid!
Every little flower, frog, bird is like getting to open a present! And even though we know that the seasons turn and all the regulars will appear in due time, we still act like it's the first! I think it's an ancestral memory thing. Water Science School.

Science Center Objects Overview Related Science Multimedia A spring is a place where water moving underground finds an opening to the land surface and emerges, sometimes as just a trickle, maybe only after a rain, and sometimes in a continuous flow.
Rainbow Springs, Florida, USA A spring is a water resource formed when the side of a hill, a valley bottom or other excavation intersects a flowing body of groundwater at or below the local water table, below which the subsurface material is saturated with water. Credit: Briant A Kimball.
Hot springs coexist with icebergs in Greenland Happy Greenlanders and tourists enjoy the unique experience of dipping in the hot springs while enjoying drifting icebergs floating by on Uunartoq Island at the far southern tip of Greenland. Credit: Wikipedia We're betting the number of places you can view icebergs while sitting in hot springs is very small!

February 20, The research also found that the passage of spring is not directly south to north but is aligned southwest to northeast, as are early spring temperatures. Comparison with previous years does suggest that spring may be moving faster now than it did in the past. For more information visit www. The House Live All. Partner content.
