- - - - More Mass⚖️
        
        More KE
    - - More Speed🏃‍♀️
        
        More KE
  - - - GPE is changed into KE gradually
      - Typical Exam Question
        
        Why does a tennis ball bounce lower each time it hits the ground?🎾
        
        Each time the ball hits the ground
        
        The ball has less KE left
        
        It will bounce to a lower height
        
        Some KE is converted into HE and SE
    - - KE is the least
      - GPE is the most
    - - KE is the most
        
        Speed is also the most🏃‍♀️
      - GPE least
  - - - Greater height🙋‍♀️
        
        More GPE
        
        More KE
        
        Greater force of impact
        
        More speed🏃‍♀️
      - More mass⚖️
        
        More GPE
        
        More KE
        
        Greater force of impact
        
        More speed🏃‍♀️
    - - Allows more KE of the falling object to convert into SE and HE
      - Less KE will have a smaller force of impact on the person's head🗣️
- - - - The stored energy is then transformed into other forms of energy to do work

    - - When wood is burnt, the chemical potential energy is released. It changes into heat and light energy.
      - When we formed a closed circuit, the chemical potential energy in dry cells is released. It changes into electrical energy.
      - when we carry out respiration, the chemical potential energy in food is released for us to do work.
  - - - Mass⚖️
        
        Mass increases
        
        GPE increases
      - Height🙋‍♀️
        
        Height increases
        
        GPE increases
    - - gravitational potential energy is the energy possessed by an object due to its position from the ground
  - - - Energy stored in elastic objects that can be...
        
        stretched
        
        compressed
        
        twisted
        
        bent
    - - examples:
        
        A twisted rubber band has elastic potential energy before it springs back to its original shape
        
        a bent diving board or a bent plastic ruler has elastic potential energy before it springs back to its original shape
        
        When the rubber band of a slingshot is stretched, it has EPE. This stored energy can then be used to make a rock move
        
        When the key of a wind-up toy car is turned, the spring inside of it is compressed and has EPE. The stored energy will then convert to its original shape and causes the toy car to move
    - - More it is compressed or stretched
        
        more EPE
