How is Kinetic Energy different from Potential Energy?

• Kinetic Energy is stored energy while Potential Energy is motion energy.
• Potential Energy is much stronger than Kinetic Energy
• Potential Energy is stored energy within an object while Kinetic Energy is energy in motion.

What is the definition of Energy?

• Energy is the ability to do WORK. It is how things CHANGE and MOVE and takes all sorts of forms.
• Energy is the strength is takes to make an object move.
• Energy is when an object is exhausted and does not move.
