Question

Q1. How much gravitational potential energy do you gain when youwalk up the CN Tower stairs (346 m)?What type of energy/energies transformed into GPE in this scenario?

Answer 1

Given data:

* The distance traveled is 346 m.

Solution:

Let m be the mass of the body.

Then, the gravitational potential energy of the body on reaching the top of the tower is,

`U=\text{mgh}`

where g is the acceleration due to gravity, and h is the height of the tower,

As mg is the weight of the body.

Substituting the known value,

`U=w*346`

where w is the weight of the body,

When a person walks to the certain height, the internal energy of the person's body is converted into the gravitational potential energy.
