Potential and Kinetic Energy

Question 1

Forms of potential energy

Answer 1

• gravitational
  
  • Potential energy that is dependent on height
  • PE(gravitational) = mgh
• elastic
  
  • Energy that is stored due to being stretched or compressed
  • e.g. stretch a rubber band
• chemical
  
  • energy stored in the chemical bonds of a substance
  • e.g. gasoline

Question 2

EP formula

Answer 2

EP = mgh

Question 3
