What is Hooke’s Law simple explanation?
Hooke’s Law is a principle of physics that states that the that the force needed to extend or compress a spring by some distance is proportional to that distance. … In addition to governing the behavior of springs, Hooke’s Law also applies in many other situations where an elastic body is deformed.
What does Hooke’s law state?
Hooke’s law, law of elasticity discovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load.
What is Hooke’s Law GCSE?
When an elastic object, such as a spring, is stretched, the increased length is called its extension. The extension of an elastic object is directly proportional to the force applied to it: F = k × x. F is the force in newtons (N) k is the ‘spring constant’ in newtons per metre (N/m)
What is Hooke’s law for stress and strain?
Hooke’s law states that the strain of the material is proportional to the applied stress within the elastic limit of that material. When the elastic materials are stretched, the atoms and molecules deform until stress is been applied and when the stress is removed they return to their initial state.
Where is Hooke’s law used?
For this reason, Hooke’s law is extensively used in all branches of science and engineering, and is the foundation of many disciplines such as seismology, molecular mechanics and acoustics. It is also the fundamental principle behind the spring scale, the manometer, and the balance wheel of the mechanical clock.
Why is Hooke’s law important?
Hooke’s Law, by Doodle Science, on youtube.com
Hookes law is important because it helps us understand how a stretchy object will behave when it is stretched or compacted. … The main component of car shocks are springs, and understanding how the spring will behave (using hookes law) is ideal for enhancing the technology.
How is Hooke’s Law calculated?
An ideal spring obeys Hooke’s law, F = -kx. Details of the calculation: k = |F/x| = (0.1 N)/ (0.035 m) = 2.85 N/m.
How is Hooke’s Law verified?
Here k is the spring constant which is a quality of each spring. Therefore, in order to verify Hooke’s Law, you must verify that the force F and the distance at which the spring is stretched are proportional to each other (that just means linearly dependent on each other), and that the constant of proportionality is k.
What is Hooke’s Law graph?
Provided that the limit of proportionality is not exceeded, a graph of stretching force against extension is a straight line through the origin, because Hooke’s Law is obeyed. … The gradient of the graph of force F, (y-axis), and extension e, (x-axis), is equal to the spring constant k.
What does F KX mean?
F=−kx. where: x is the displacement of the spring’s end from its equilibrium position (a distance, in SI units: meters); F is the restoring force exerted by the spring on that end (in SI units: N or kg·m/s2); and. k is a constant called the rate or spring constant (in SI units: N/m or kg/s2).
What is the formula for work done?
The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work. A newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules.
What is transferred when work is done?
Work is the measure of energy transfer when a force (F) moves an object through a distance (d). So when work is done, energy has been transferred from one energy store to another, and so: energy transferred = work done.
What are the 3 types of stress?
Stress management can be complicated and confusing because there are different types of stress — acute stress, episodic acute stress, and chronic stress — each with its own characteristics, symptoms, duration and treatment approaches.
What is strain formula?
Strain occurs when force is applied to an object. Strain deals mostly with the change in length of the object. Strain = Δ L L = Change in Length Original Length . … Strain=LΔL=Original LengthChange in Length.
