HELP ASAP FAST PLEASE I NEED HELP Mechanical energy is defined as

Question 1 options:

the energy of motion and position, which is represented by the formula KE + PE = ME

potential energy

Energy of motion

Energy of machines and tools

We know that potential energy is the stored energy in an object. In a stretched rubber band or compressed spring that stored energy is due to the objects tendency to return to its original shape, we call that elastic potential energy. What do you call the type of potential energy invested in an object by lifting it against the force of gravity?

Question 2 options:

ground energy

law of conservation of energy

power

gravitational potential energy

How can you increase the gravitational potential energy (GPE) of an empty shoe box on the bottom shelf of a bookcase?

Question 3 options:

all of the options listed here will increase the GPE

raise the box to a higher shelf

add items to the box to increase its mass

add items to the box and raise it to a higher shelf
