When a person holds an object, it has potential energy. how will the potential energy change if the person lifts the object above his or her head?
a. the object's potential energy will be zero.
b. the object's potential energy will be the same.
c. the object's potential energy will be less.
d. the object's potential energy will be greater.

D. The objects potential energy will be greater.

Explanation:

Potential energy is expressed in

PE = mgh

Where PE is the product of mass of the object, g which is acceleration to gravity and height.

PE and height is directly proportional which means that any changes in height will change the value of the PE. Increase in height means increase in PE.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
