A0.19-kg stone is held 1.1 m above the top edge of a water well and then dropped into it. the well has a depth of 4.6 m. relative to the configuration with the stone at the top edge of the well, what is the gravitational potential energy of the stone−earth system before the stone is released?

2.048 J

Explanation:

mass of stone, m = 0.19 kg

h = 1.1 m

g = 9.8 m/s^2

Gravitational potential energy, U = m x g x h

U = 0.19 x 9.8 x 1.1

U = 2.048 J

Thus, the potential energy of the stone is 2.048 J.

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
