... motion. From the position data we can get the velocity and the acceleration at each instant. For a full description, we also need to know the MASS of the object. We get this by using a balance to compare the object to objects with known mass. All such sets of objects of known mass have been compared ...

... A particle of mass m is undergoes oscillatory motion if, on displacement from its equilibrium position, it experiences a restoring force proportional to its displacement – the well known simple harmonic motion. The equation of motion is d 2x m 2 m 2 x, dt where is the natural frequency of osci ...

... Note that factor label of the units gives N/kg, but that is equivalent to m/s/s since F=ma and the units are F (in N) = m (in kg) a (in m/s/s). Now, using the formula for critical velocity: (Consider that g is the centripetal acceleration, and the formula becomes apparent. While normally we don't co ...
