Question

An apple with a mass of 0.15 kg rests on the edge of a desk 0.65 m above the

floor. Given that the acceleration due to gravity is 9.8 m/s2, what is the apple's
potential energy?

Answer 1

The apple's potential energy is 0.9555 Joule

Step-by-step explanation:

Answer 2

The apple's potential energy is 0.9555 Joule

Step-by-step explanation:

Gravitational Potential Energy

Gravitational potential energy is the energy stored in an object because of its vertical position or height in a gravitational field.

It can be calculated with the equation:

`U=m.g.h`

Where m is the mass of the object, h is the height with respect to a fixed reference, and g is the acceleration of gravity, or 9.8 m/s^2.

The apple has a mass of m=0.15 kg and it's located at a height of h=0.65 m. Calculate the potential energy:

`U=0.15\ kg\cdot 9.8\ m/s^2\cdot 0.65\ m`

`U=0.9555\ J`

The apple's potential energy is 0.9555 Joule
