Physics

• All objects have energy
• Energy is the ability to do work.
• Energy cannot be created or destroyed.
• When energy is passed from one object to another, it is said to be transferred.
• What are the types of potential energy?

  Gravitational, elastic, chemical, nuclear.
• All energy is derived from the Sun.
• Plants soak up solar energy from the sun and change it into chemical energy
• Animals obtain energy by eating plants or other animals
• Kinetic energy: Energy of movement
• Potential energy is the energy stored in an object due to its position or shape.
• What is the most important type of energy?
