Advantages and disadvantages of motion energy

Motion energy is also known as mechanical energy is the energy stored in moving objects. As the object moves faster more energy is stored. Motion energy is also known as the sum of potential and kinetic energy in an object that is used to do work.

Pros OR Advantages of motion energy:

  • Motion energy helps us walk on the ground.
  • Some time friction is responsible for many types of motion.
  • Breaks in a car make use of friction to stop the car.
  • motion energy helps in the generation of heat when we rub our hands.

Cons OR Disadvantages of motion energy:

  • The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects.
  • A lot of money goes into preventing friction and usual wear and tear caused by it by using techniques like greasing and oiling.
  • It always resists the motion so extra energy is required to overcome it.
