While standing at the top of the stairs,you have a potential energy of 40 Joules.If you walk all the way down the stairs,what would your potential energy be at the bottom of the stairs?

Question

Quizplus · Accepted Answer

Potential energy depends on the height of an object and its mass. As the question provides no information about the mass of the person, we can assume that it remains constant. Therefore, the potential energy will depend only on the height of the object, which is at maximum at the top of the stairs.

At the top of the stairs, the potential energy is 40 Joules. As the person walks down the stairs, the height decreases, and hence the potential energy also reduces. When the person reaches the bottom of the stairs, the height becomes zero, and hence the potential energy also becomes zero. Therefore, the answer is A) 0 Joules.
