physics chapter 7: energy - Coggle Diagram

- - - - the amount of energy in a kinetic energy store can be measured using a formula which states Ek=0.5mv2, Ek is the energy in the kinetic store in joule (J), m is the mass in kg, v is the speed of the body in m/s
      - the amount of energy in a gravitational potential store can be measured with a formula which states Ep=mgh, where Ep is the energy in the gravitational potential store measured in joule(J), m is the mass of the object measured in kg, g is the gravitational field strength measured in N/kg, and h is the height above ground level, measured in metres(m)
        
        only changes in gravitational potential energy matter, the level of zero gravitational potential energy can be assigned to any point that is convenient
