what is potential energy

• capability of doing work given a position

• capability of doing energy

• capability of doing work given a position or condition

Choose which one is a conservative force:

• work

• potential energy

• kinetic energy

• energy

friction forces are no conservative forces ?

• true

• false

the work done by the non conservative forces can be restored?

• true

• false

what does the energy conservation principle stablish?

• energy cannot be created or destroyed only transformed

• energy can be created or destroyed

• enery only can be created

• energy only can be destroyed

The total energy is the sum of potential energy and kinetic energy?

• true

• false

The potential energy is represent by the letter:

• E

• P

• K

• U
