Free vibrations involve no transfer of energy between the vibrating object and its surroundings, whereas forced vibrations occur when there's an external driving force and thus transfer of energy between ...

It is a frame of reference in which Newton's first law, which states that objects won't change velocity (accelerate) unless an external force acts upon them, is obeyed.

Simple harmonic motion is an oscillation where both of the following statements are true:

-The acceleration of an object is directly proportional to its displacement from an equili...

Electron volts, like joules, are a unit of energy. This may sound confusing- why two? But think of it this way; length has two possible units- metric (metres) and imperial (inches). We can use either unit...

To understand this question, we have to consider the wave-particle duality of electrons. When passing through a slit, electrons exhibit a wavelike property- they diffract or spread out like a wave passing...
