This elastic potential energy is converted into kinetic energy when the rubber band is released. When a rubber band is stretched the potential energy is inbuilt in the rubber band which is equal to half times the elastic constant and the square of the change in length of the rubber band on stretching and is called the elastic potential energy due to elasticity of the rubber. The rubber is an example of an elastic material that regains its original shape and size after being stretched. While walking down the stairs, the force due to the gravity was also acting on the slinky that made the coil collapse together one above the other and there was no chance for the mass or the energies to balance out and attain the equilibrium state. On reaching the plane ground, the slinky comes to a rest at the equilibrium position, distributing equal energies on both the ends and the balance is created. This is how the slinky is able to walk down the steps independently. The kinetic energy is then converted into potential energy and supplies enough potential to the slinky to raise its topmost end and step onto the next. This is because, for the coils of the slinky to collapse from one end to another, the potential energy stored is converted into kinetic energy. You will observe that the slinky will walk down the stairs by itself without applying any external force to it. If you have a slinky, place it on the step of your staircase and drag another end of the slinky to one step down and leave it. When enough potential energy is stored into a ball, means when all the kinetic energy of the ball is converted to the potential energy, the ball is held stable in the air for a few milliseconds and then returned towards the grounds due to the gravitational pull and is called the free fall of the ball.īut due to the free fall of the ball, it still has potential energy associated with it and hence it bounces back after bouncing the ground converting its potential energy to kinetic energy. As the height of the ball above the ground increases, the kinetic energy of the ball is converted into potential energy. When you throw the ball high up in the air, it raises high due to the potential energy applied to a ball in a particular direction being changed to the kinetic energy,and hence the ball accelerates in the air. The freefall of a ball Change in the form of energies of ball thrown in the air But still, the car does not sweep down is only because of the potential energy that keeps the car in a steady position. Plus the frictional force on being in contact with the metallic road and the air resistance drags the car backward. The force due to gravity is acting slightly backward that would result a car tosweep down the hill. A car parked on the top of the hill Car parked on the hill body diagramĬonsider a car parked on the top of the hill on a steeper road as shown in the diagram above. More the quantity of water more will be the effect observed. As the density of water is less than the plates floating on the asthenosphere, hence the gravitational pull effects exerted on the Earth by the Moon is seen on the oceanic water developing tides. The potential energy present in the ocean current is due to the gravitational potential energy as well as the tidal energy. The ocean current generates enough energy which is also used to run a turbine to generate electricity. Until the water is stored in the dam, it keeps on adding the gravitational potential energy until the volume of the water reserved in between a sturdy construction is stable, and when released, the potential energy of the water is converted into kinetic energy and water flows from the dam. Water Stored in the DamĪs the volume of the water stored in a dam rises and the point of elevation of the water level in the dam goes high, the potential energy of the volume increases. Work done is equal to the potential energy released. Potential energy is required to lift the heavy load is equal to the weight of the load due to the force of gravity acting downward and the height at which the weight has to be raised and can be represented as The following is a list of examples that exhibits the potential energy:- Man Lifting a WeightĪ man receives the potential energy that he receives from the food that he intakes and is stored in the form of chemical potential energy. In this article, we are going to discuss some examples of potential energy in details.
