The negative sign shows that the restoring force is opposite to the displacement. Mass m 5 kg.
It is expressed in newton per meter n m.
K constant physics formula. The boltzmann constant k b or k is the proportionality factor that relates the average relative kinetic energy of particles in a gas with the thermodynamic temperature of the gas. Hooke s law gives the force a spring exerts on an object attached to it with the following equation. Mean free path is given by.
In the equation f elect k q 1 q 2 d 2 the symbol f elect represents the electrostatic force of attraction or repulsion between objects 1 and 2. The coulomb constant the electric force constant or the electrostatic constant denoted ke k or k is a proportionality constant in electrostatics equations. Mean free path physics definition formula kinetic theory of gases.
N s 2 c 2 c2. The spring constant formula is given as k frac f x where f force applied x displacement by the spring. λ frac k t sqrt 2 pi sigma 2 p where σ diameter of the molecule p pressure of the gas t temperature and k boltzmann s constant.
In si units it is equal to 8 987 551 7923 14 109 kg m3 s 2 c 2. The symbol k is coulomb s law constant 9 x 10 9 n m 2 c 2 q 1 and q 2 represent the quantity of charge on object 1 and object 2 and d represents the separation distance between the objects centers. It occurs in the definitions of the kelvin and the gas constant and in planck s law of black body radiation and boltzmann s entropy formula the boltzmann constant has the dimension energy divided by temperature.
Mean free path formula physics. Determine its spring constant. Mean free path λ t and.
F kx the minus sign shows that this force is in the opposite direction of the force that s stretching or compressing the spring. Example 1 a spring with load 5 kg is stretched by 40 cm. Ev å e 2.
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 f s kx 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.
