energy charges

• explain the energy transfer

  the kinetic energy of the vehicle decreases

  thermal (internal) energy increases and goes into surroundings

  sound increases

  when the vehicle stops kinetic energy is 0

  
• ball hitting a wall

  kinetic energy decreases

  internal energy increases

  sound increases

  
• evaluate the energy transfer of the tennis ball being thrown upwards

  chemical energy of the person decreases

  the kinetic energy of the ball increases

  the gravitational potential energy increases

  when the ball hits the ground ,internal energy increases

  
• evaluate the energy change

  chemical energy of the wood decreases

  the thermal energy of the water increases

  the water gains kinetic energy of the water increases

  
• evaluate the energy transfer

  the chemical energy of the cyclists muscles decreases

  the kinetic energy of the bicycle increases

  the internal energy from the wheels of the bike on the the road increases due to friction

  some thermal energy is lost to the surroundings

  
• coal fired plants produce electricity by burning coal, evaluate energy changes

  the chemical energy of the coal decreases

  the internal energy of the water increases

  the kinetic energy of the water increases (boiling)

  the kinetic energy of the turbine increases

  the thermal energy of the water and steam decreases

  some of the thermal energy is lost to the surroundings or environment
