Examples of Work and Energy

 

Work:

• Pushing a shopping cart at the grocery store is an example of work. 
• The force applied to the cart to move it is work being done.
  Turning a doorknob to open a door is another example of work.
• The force applied to the doorknob is work being done.
  

Energy:

• A rollercoaster ride is an example of energy in motion. The potential energy stored in the rollercoaster due to its height is converted into kinetic energy as it moves down the track.
• A battery-operated toy car is another example of energy in motion. The chemical energy stored in the battery is converted into kinetic energy to make the car move.
• A falling apple is an example of potential energy being converted into kinetic energy. As the apple falls, its potential energy due to its height decreases, while its kinetic energy increases.
