NEET Physics Notes Oscillations-Series Combination of Springs
Series Combination of Springs
If two springs of spring constants k1 and k2 are joined in series (horizontally and vertically), then their equivalent spring constant ks is given
Parallel Combination of Springs
If the two springs of spring constants k1 and k2 are joined in parallel as shown, then their equivalent spring constant kp = k1 + k2 hence,
Force and Energy in SHM
We know that, the acceleration of body in SHM is
is a constant and sometimes it is called the elastic constant. In SHM, the force is proportional and opposite to the displacement.
If a particle of mass m is executing SHM, then at a displacement x from the mean position, the particle possesses potential and kinetic energy.
If there is no friction, the total mechanical energy, E = K + U, of the system always remains constant even though K and U change.
