What is the difference between potential energy and kinetic energy?

​Could you decide where was the maximum potential energy and when was the maximum kinetic energy?

​Could you decide where was the maximum potential energy and when was the maximum kinetic energy?

Type some forms of Potential energy.

(Hint: We have about 6 forms)

​Gravitational Potential Energy

​When objects have the potential to change their position due to the force of gravity

Open Ended

What do you think affects the gravitational potential energy?

• The height above the surface.

• The mass of the object affects

​Factors affecting the gravitational potential energy

​Chemical Potential Energy

​When the energy is stored within the matter itself (for example, energy stored in a battery).

When a battery is connected to a closed circuit to power an object, electricity can flow and potential energy is changed to the kinetic energy of an electric current.

​Elastic Potential Energy

Elastic potential energy is when it is stretched or compressed within the object (for example, a stretched string on a bow about to shoot an arrow).

​Magnetic Potential Energy

When certain metal objects in a magnetic field have the potential of changing their position due to the force of magnetism.

​sTATIC Potential Energy

When charged particles in an electrostatic field have the potential of moving toward the opposite charge or away from the same charge.

​Scientists measure both potential and kinetic energy in joules (J)

​DO YOU REMEMBER WHAT IS THE LAW OF CONSERVATION??

​Energy can be neither created nor destroyed, but it can be transformed from one form to another.
