What is the formula for elastic force?
Hooke’s law gives us the force we need to find elastic potential energy. Looking at a graph of force versus displacement, we can find that the formula for elastic potential energy is PE = 1/2(kx^2).
What is the elastic force?
Something that is elastic can return to its original shape after being stretched or compressed. This force is called elastic force. The farther the material is stretched or compressed, the greater the elastic force becomes.
What is Hooke’s law of elasticity?
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.
Is spring force elastic?
Since the spring is now compressed, there will be elastic spring force acting on the spring (upwards) to return the spring to its original length. This causes the spring to be compressed more and decreases in length.
Is Elastic a contact force?
Contact Forces. Contact forces are forces in which two or more objects or bodies touch or contact each other directly. There are many kinds of contact forces; among the most familiar are friction and elastic forces. Air resistance, a special type of friction, also is a contact force.
What is work formula?
Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d).
Is gravity an elastic force?
The universal law of Gravitation states that the force of gravity acts between all objects in the universe. compression and tension are two types of elastic forces. Compression is an elastic force that squeezes or pushes matter together and tension is an elastic forcce that stretches or pulls matter.
What are two types of elastic forces?
Matter is elastic if it returns to its original shape after it is squeezed or stretched; There are two types of elastic forces- compression and tension.
Is elastic force conservative?
Other examples of conservative forces are: force in elastic spring, electrostatic force between two electric charges, and magnetic force between two magnetic poles.
What are the three modulus of elasticity?
The three types of elastic constants are: Modulus of elasticity or Young’s modulus (E), Bulk modulus (K) and. Modulus of rigidity or shear modulus (M, C or G).
Which is more elastic rubber or steel?
So, it can be said that for a given amount of stress, the strain produced in the steel is comparatively smaller than the strain produced in the rubber. Therefore, with the help of Young’s modulus, it can be concluded that steel has greater elasticity than rubber.
What is the SI unit of Young’s modulus?
Young’s modulus = stress/strain = (FL)/A(Ln − L). This is a specific form of Hooke’s law of elasticity. The units of Young’s modulus in the English system are pounds per square inch (psi), and in the metric system newtons per square metre (N/m2).
What is elastic limit?
A material’s elastic limit is the greatest stress that can be applied to it without causing plastic (permanent) deformation. When a material is stressed to a point below its elastic limit, it will return to its original length once the stress is removed.
Is spring force constant?
The force exerted by a spring on objects attached to its ends is proportional to the spring’s change in length away from its equilibrium length and is always directed towards its equilibrium position. The proportional constant k is called the spring constant.
