Question

Which change would cause the largest increase in a mountain climber’s gravitational potential energy?

Answer 1

carrying twice the weight and climbing twice as high

Answer 2

Answer : The correct option is (c).

Explanation :

The energy which is due to the height of an object under the action of gravity is called gravitational potential energy.

Mathematically, it can be written as :

P = m g h

Where,

m is the mass of the object

g is the acceleration due to gravity

h is the height of the object from the reference level

So, potential energy is directly proportional to both the mass and the height.

The statement about the largest increase in a mountain climber’s gravitational potential energy is "carrying twice the weight and climbing twice as high".
