K Value Physics Spring

The law is named after 17th century british physicist robert.

K value physics spring. Where fspring is the force exerted upon the spring x is the amount that the spring stretches relative to its relaxed position and k is the proportionality constant often referred to as the spring constant. Hooke s law gives the force a spring exerts on an object attached to it with the following equation. Determine the amount of the potential energy to force the. How to calculate a spring constant using hooke s law.

It is different for different springs and materials. Consider two springs with different spring constants k 1 and k 2. Pe k x 2 250 0 1 2 125 0 01 1 25 joule. The size of the relationship between the extension and the restoring force of the spring is encapsulated in the value the spring constant k.

Can the spring constant k be negative. The spring constant shows how much force is needed to compress or extend a spring or a piece of elastic material by a given distance. Also the displacement is 30 0 cm 0 30 m. Determine the equivalent spring constant when the two springs are connected in parallel.

F k x. Hi i found a difficulty when solving this problem from my textbook. Hooke s law is a law of physics that states that the force f needed to extend or compress a spring by some distance x scales linearly with respect to that distance that is where k is a constant factor characteristic of the spring i e its stiffness and x is small compared to the total possible deformation of the spring. Thus putting the values in the above formula we get k frac 9000 0 30 i e.

Determine the equivalent spring constant when the two springs are connected in series. The spring constant is a positive constant whose value is dependent upon the spring which is being studied. To solve for the spring constant k we can rearrange the formula for spring constant as. An athlete jumps onto a spring instrument with a weight of 500 n the spring shortens 4 cm.

K frac f x in this example a 9000 n force is pulling on a spring. It means that the spring pulls back with an equal and opposite force of 9000 n. Any physicist knows that if an object applies a force to a spring then the spring applies an equal and opposite force to the object. The spring constant k is a measure of the stiffness of the spring.

F kx. In the arrangement of figure 7 11 which is basically a standard block attached to spring resting horizontally we gradually pull the block from x 0 to x 3 0 cm where it is stationary. K f x 5 0 02 250 n m.
