A woman with a mass of 65kg climbs a set of stairs that are 3m high. How much gravitational potential energy does she gain?

Thank you.

To calculate the gravitational potential energy gained by the woman, you can use the equation:

Gravitational Potential Energy (GPE) = mass × gravitational acceleration × height

Given:
- Mass of the woman (m) = 65 kg
- Height of the stairs (h) = 3 m
- Gravitational acceleration (g) = 9.8 m/s² (approximate value)

Plugging in the values into the equation:

GPE = 65 kg × 9.8 m/s² × 3 m

Calculating:

GPE = 1914 Joules

Therefore, the woman gains approximately 1914 Joules of gravitational potential energy when climbing the stairs.

To calculate the gravitational potential energy gained by the woman, you can use the equation:

Gravitational Potential Energy = mass × height × gravitational acceleration

where:
mass = 65 kg (given)
height = 3 m (given)
gravitational acceleration = 9.8 m/s² (standard on Earth)

Substituting the given values into the equation, we have:

Gravitational Potential Energy = 65 kg × 3 m × 9.8 m/s²

Calculating this expression will give you the gravitational potential energy gained by the woman.

65 * 9.8 * 3 Joules
