Friction force A block of mass m projected onto a rough surface will be brought to rest by the kinetic friction force.
The position of the mass at this point is called the equilibriumposition. If the mass is moved either up, which compresses the spring, ordown, which stretches it, the spring exerts a force on the mass to equilibriumposition. The objective of this experiment is to determine the relationshipbetween the force and the displacement of a spring.
When experiment has done,it can be conclude that this experiment follows the Hooks Law which Hooks Law states that the spring exerts it force in the direction opposite the displacement, acting to return it to its natural length oof spring also increase.
But each spring has a spring constant to show its capability to support the mass. When the mass is greater than spring constantspring will be lose elasticity. Consequently,spring can return to natural length and maintain that form.
The simplest form of periodic motion is represented by an object oscillating on the end of a uniform coil spring. Because many other types of vibrational motion closely resemble this systemwe will look at it in detail. We assume that the mass of the spring can be ignored, and Experiment to prove hookes law the spring is mounted horizontally, so that the object of mass m slides without friction on the horizontal surface.
Any spring has a natural length at which it exerts no force on the mass m. The position of the mass at this point is called the equilibrium position. If the mass is moved either to the leftwhich compress the springor to the right, which stretches it, the spring exerts a force on the mass that acts in the direction of turning the mass to the equilibrium position; hence it is called a restoring force.
We consider the common situation where we can assume the magnitude of the restoring force F is directly proportional to the displacement x the spring has been stretched or compress from the equilibrium position: We will determine the spring constant, kfor an individual spring using both Hookes Law.
Secondly, this experiment is also conducted to see whether the spring constant gives any effect on the value of displacement. If w is not so large as to permanently, distort the spring, then the force,F will restore the spring to its original length after the load is removed.
F is thus is called an elastic force and it is well known that the magnitude of an elastic force and it is well known that the magnitude of an elastic restoring force is directly proportional to the stretch. An additional approach is possible.
One definition of simple harmonic motion SHM is that it is motion under a linear, Hookes Law restoring force. For such a motion it have from Newtons Second Law. The provides an additional method for testing whether the spring obeys Hookes Law. The hanger was hang assembly on the notch of the Hookes Laws apparatus.
The scale was adjusted vertically, so that the 0cm mark is parallel to the disc. The previous step has been repeated until all masses has been removed.
In general, what pattern do you notice between the force due to gravity of the masses and the displacement of the spring?
Dont forget to include units on all number! What is the physical meaning of the slope for the force-displacement graph? What is the physical meaning of the vertical intercept for the force-displacement graph?
Using this equation, what would be the force required to stretch the spring 10 cm? What would be the displacement of a g mass? The force due to gravity of the masses and the displacement of the spring is linear.
From the graph, physical meaning is the force due to gravity of the masses over displacement of the spring. It mean that, the slope is spring is constant, k.
H mean that the spring have loosen its strength because it had been use many time before and rate of error is higher. Where F is the force, k represent spring constant and x is the size of displacement.described by Hooke’s Law give rise to oscillatory, simple harmonic motion.
Most systems that exhibit oscillatory behavior can, to a very good approximation for small perturbations, be described by Hooke’s Law. Hooke’s Law.
Hooke’s Law is a scientific law which concerns itself with the elasticity of materials. It states that when a force is applied to a spring, the displacement of that spring will be directly proportional to the amount of force applied. 02 forces - hookes law.

This experiment is designed to prove Hooke's Law that all springs have a spring constant using Hooke's Law's formula F=kx. Objective: y To investigate how a spring behaves if it is stretched under the influence of an weight.
this relationship can be expressed as F = kx where k is the spring constant or rather the proportionally constant and x. The experiment defines elasticity which is the ability of an object to return to its original length and shape after the deforming forces are removed. It also makes use of the Hooke’s Law to observe the elasticity of a spring.
Young's modulus can be defined at any strain, but where Hooke's law is obeyed it is a constant. We can directly obtain the spring constant k k k k from the Young's modulus of the material, the area A A A A over which the force is applied (since stress depends on the area) and nominal length of the material L L L L.
