What is the definition of elastic force?
When an elastic material is stretched or compressed, it exerts elastic force. Here, the force for which the spring regains its original shape and size is the elastic force. Definition: Within elastic limit if the size and shape of a body is changed and the force due to which the body regains its original shape and size is called the elastic force.
Is elastic force and spring force the same?
In part 2, the forces in the spring are the tension and the elastic force, in the blocks are mg/2 and the tension. As the tension is the same in the spring and blocks tension=mg/2. In the spring we have tension=elasticforce => mg/2=kx' => x'=mg/2k.
What is the equation for elastic energy?
The elastic potential energy equation is: U=1/2 k∆x 2. Where, U is the elastic energy, ∆x is the change in position, and. k is spring constant. If you want to calculate the total force required to compress or extend an object, use our Hooke’s Law calculator. How to calculate elastic potential energy? The elastic potential energy can be ...

What is the elastic force?
Elastic Force The force that allows some materials to return to its original shape after being stretched or compressed.
What is the equation for force on an elastic material?
F = kxMathematically, Hooke's law states that the applied force F equals a constant k times the displacement or change in length x, or F = kx. The value of k depends not only on the kind of elastic material under consideration but also on its dimensions and shape.
What is the formula for the force of a spring?
F = – kxThe spring force formula is expressed through the equation: F = – kx.Jun 4, 2018
How do u calculate force?
The force formula is defined by Newton's second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.Feb 15, 2022
What is the formula of strain?
The strain formula is: S = \frac{\Delta x}{X} Here, S = strain (it is unitless) \Delta x = change in dimension. X = original dimension.
How do you calculate elastic potential energy?
Elastic potential energy is equal to the force times the distance of movement. Elastic potential energy = force x distance of displacement. Because the force is = spring constant x displacement, then the Elastic potential energy = spring constant x displacement squared.
How do you calculate the force needed to stretch a spring?
F = -kx. The proportional constant k is called the spring constant. It is a measure of the spring's stiffness. When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction towards its equilibrium position.
How do you calculate spring k?
W = kx. W is the weight of the added mass. Therefore, the spring constant k is the slope of the straight line W versus x plot. Weight is mass times the acceleration of gravity or W = mg where g is about 980 cm/sec2.
Elastic Formula - Definition, Elastic Equation, Examples
As a physics student, you must have definitely heard of elastic formula. Similarly, you must know that there are basically two types of a collision which are elastic and inelastic collision. Therefore, in this article, we will study about elastic collision formula and its application.

Rahul Kala, in On-Road Intelligent Vehicles, 2016. 11.6.3 Internal Forces. The internal force is the elastic force acting on the elastic strip which attempts to make the strip contract to the smallest possible size. The difference between the natural length of the strip and the expanded length gives rise to a tension which moves each of the points on the elastic strip towards each other to ...
What is the equation for elastic collision?
An elastic collision is a collision where both the Kinetic Energy, KE, and momentum, p are conserved. In other words, it means that KE 0 = KE f and p o = p f. When we recall that KE = 1/2 mv 2, we will write 1/2 m 1 (v 1i) 2 + 1/2 m 2 (v i) 2 = 1/2 m 1 (v 1f) 2 + 1/2 m 2 (v 2f) 2. Thus, we see that the final total KE of the bodies is similar to the initial KE of these two bodies. Moreover, as p = linear momentum = mv, then we will write m 1 v 1i + m 2 v 2i = m 1 v 1f + m 2 v 2f.
What is the difference between an elastic and an inelastic collision?
Te elastic collision refers to a collision process where there is no loss in energy whereas the inelastic collision occurs with loss in energy of the system of the two objects that collide.
What is the internal force of an elastic strip?
The internal force is the elastic force acting on the elastic strip which attempts to make the strip contract to the smallest possible size. The difference between the natural length of the strip and the expanded length gives rise to a tension which moves each of the points on the elastic strip towards each other to contract to the minimal length. In the absence of external forces, this force would make a straight-line connection between the source and the goal, which minimizes the path length. The resultant force, however, is a mixture of the two forces, internal and external, based on which every point on the elastic strip moves. Hence, a balance of the two forces keeps the trade-off between the path length, clearance and smoothness.
What is the resultant force?
The resultant force, however, is a mixture of the two forces, internal and external, based on which every point on the elastic strip moves.
Does elastic force depend on displacement?
In a SDOF system, the elastic force depends only on one displacement. Apparently, in a MDOF system this force will depend on all the displacements. Thus, for a linear system, the superposition principle allows writing
Is elastic force entropic or entropic?
As already mentioned in Section 9.1, the elastic force is largely entropic in origin. More specifically, it arises primarily from the fact that stretching an elastomer decreases the entropy of its constituent chains, since the probability of any specific spatial arrangement or configuration of a chain decreases significantly with increase in its end-to-end separation r.2 Such changes in r, however, can cause a change in the energy as well as the entropy of a network chain since the dimensional changes require changes in conformation. Also, it is known that different conformational states (generally trans, gauche positive and gauche negative) usually correspond to different energies, because of different steric and Coulombic interactions between proximate parts of the chain. 8 Thus the elastic force may also have a significant energetic component, although it is predominantly entropic in origin.
Elastic Potential Energy Formula
Before we start with the elastic potential energy formula, let us have a look at the definition and the meaning of elastic potential energy.
What is Elastic Potential Energy Formula?
Let us understand what is potential energy formula. So, the elastic potential energy formula can be derived from the fundamental equation of elastic force. We know that the external force applied to an elastic body is directly proportional to the total displacement in the position. Mathematically, we write:
Elastic Potential Energy Examples

What is elastic force?
Just so, what is a elastic force? Something that is elastic can return to its original shape after being stretched or compressed. This property is called elasticity. As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction.
What are some examples of elastic forces?
An example of elastic force is bungee jumping. The elastic cord creates resistance and imposes a force when the cord is stretched far enough. The farther the elastic is stretched, the more force it exerts to return back to its original shape. What are two types of elastic forces?
How to find force in math?
The formula for force says force is equal to mass (m) multiplied by acceleration (a). If you have any two of the three variables, you can solve for the third. Force is measured in Newtons (N), mass in kilograms (kg), and acceleration in meters per second squared ( m/s2 ). Simply so, what is an example of elastic force?
