lucy picks up an object from the floor. how will the potential energy change if lucy lifts the object above her head.
When Lucy picks up an object from the floor and lifts it above her head, the potential energy of the object will increase. Potential energy is directly proportional to the height above the ground, so as Lucy lifts the object higher, the potential energy of the object will increase correspondingly.
The potential energy of an object changes with its position relative to a reference point. In this case, let's assume the reference point is on the floor.
When Lucy picks up the object from the floor, she is increasing its vertical height. As a result, the potential energy of the object increases. This is because the potential energy of an object is directly proportional to its height above the reference point.
So, as Lucy lifts the object above her head, the potential energy of the object will increase.
