A spring stretches because the coiled spring stores potential energy. This energy is released as the spring is stretched and returns to its original shape. Over a period of time, the spring becomes worn and loses the potential energy.
Every spring has its natural length. The spring can be stretched to increase its length and compress it to decrease it. When a spring is stretched(i.e. mass is added) the spring pulls the mass added but this force is not enough to keep the spring in its natural length or in layman's language it is less than the weight of mass added that's why it is stretched. Of you're not satisfied by the answer do your own research on Wikipedia.
It is found that period of oscillation of a spring with mass attached is given as T = 2 pi ./ (m/k)
Here m is mass attached and k is spring constant
So as m increases period has to increase.
The physical significance of the spring constant is the characteristics of the spring. Hooke's law states that the force needed to compress or extend a spring by a specific distance is proportional to that distance.
The stretch or compression of a spring is defined by Hooke's Law,where F is the Force acting on the spring,k is the constant spring factor, based on the material and construction of the spring.x is the displacement of the spring.The formula holds true until, or unless the force permanently deforms the spring material.
In mechanics, and physics, Hooke's law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load added to it as long as this load does not exceed the elastic limit. So if you keep inside the load limit of the spring, the spring will return to it's original shape. As soon as you exceed that load the spring will stretch and not return to it's original shape
some are but not all "Sir Legna Added" No, trampolines are more like a spring machine due to there reactions. A pulley is more used for lifting weight.
There are many possible errors in a Hooke's law experiment. Examples of some common errors are: Not reading the ruler correctly when measuring the extension of the spring. Not starting the timer at exactly the same time as when the weight is added to the spring. Not adding the weights in a smooth, continuous motion. Not adding the same amount of weight to each spring. The spring could be damaged or broken, which would affect the results. Other sources of error could include: The spring could be old and not have the same elasticity as a new spring. The spring could be of a different material than what is expected, which would affect the results. The experiment could be done in a place with a lot of vibration, which would affect the results.
Clock time doesn't change; each day is 24 hours long except when leap seconds are added or subtracted; this is infrequent and usually happens New Year's Eve. The period of sunlight begins to get longer than the period of dark when spring begins.
(any period) Electrons are added to the same shell, therefore the nuclear charge is greater. Electrons are closer to the nucleus so have a greater attraction to the neucleus as you go across a period. (enough to get you 3 marks, use this always for this type of question).
A period can be added
Slaked lime is added to water after chlorination as a coagulant to destabilize the electrostatic charges of suspended particles in the water.
Mineral water has minerals added, as where spring water is directly bottled at source without added minerals or vitamins
Closing balances on cash flow are opening balances for the next period and therefor added
They are grown suspended in water, the water has the correct nutrients added to enable the plant to thrive.
A suspended chord, or 'sus' chord produces a sound that almost demands being followed by a finishing chord to complete the sound. Specifically, a suspended chord is played without the 3rd tone with the perfect 4th tone being added. So, a G suspended chord is the above in the key of G. The notes are G, C, D.
Any integer greater than +7.
If a positive and negative number are added together, and the positive number has a greater value, the sum will be positive.
The physical significance of the spring constant is the characteristics of the spring. Hooke's law states that the force needed to compress or extend a spring by a specific distance is proportional to that distance.
Grace period is a time that is added after the deadline of a project or a task has been determined.
