  • Light is an example of a transverse wave.
• Longitudinal wave: The wave in which the movement of the particles is parallel to the motion of the energy is called a longitudinal wave.
  • The sound wave is an example of a longitudinal wave in general.
• The ability to do something or act in a particular way is called Power.
• Force is the push or pulls on an object with mass that causes it to change velocity.
• Momentum is the product of the mass and the velocity of an object or particle. It is a vector quantity.
