Memahami Energi Kinetik dan Energi Potensial

[Music] imagine you have a ball which you throw upwards as the ball travels upwards we say that it has kinetic energy kinetic energy is a form of energy possessed by a body due to its motion therefore anything that moves has kinetic energy such as a car traveling on the road and a plane flying in the sky even you possess kinetic energy when you walk or run in fact the faster a body moves the greater its kinetic energy therefore when you run you have more kinetic energy than when you walk when the body stops there is no more kinetic energy when you come to a star or when the car stops moving kinetic energy becomes zero if we now raise the ball to a certain height and release it what happens it starts falling downwards right it starts from a position of rest and then gains speed when you let it go in other words it starts with zero kinetic energy and then gain some kinetic energy where does this kinetic energy come from this energy which is stored in the ball is called potential energy potential energy is a form of energy stored in a body due to its position let's have a closer look here the position is the balls height from the ground when you release it the potential energy converts to kinetic energy in fact the higher the ball the larger its potential energy that is why if we raise the ball to a greater distance from the ground and release it it will hit the ground harder let's look at another example look at this slingshot it has stored energy with which it can throw the bird up to a certain distance based on its position in the slingshot we can say the bird has potential energy as soon as it's released from the slingshot it gains kinetic energy and because of kinetic energy it is able to apply force on the little houses to break them down time for an exercise who has the greatest potential energy bubbles as the most potential energy because she is at the top we know that potential energy increases with the increase in the distance of a body from the ground let's summarize potential energy is the energy of a body due to its position kinetic energy on the other hand is the energy of a body due to its motion potential energy mostly depends on the distance of a body from the ground kinetic energy depends on its speed
