find gravitational potential energy!
you!

Explanation:

Gravitational Potential Energy

It's the capacity of an object to do work due to its relative height from a fixed reference point.

It's computed as

GPE=m.g.h

Where m is the mass of the object, h is its height and g is the acceleration of gravity,

The mass of water is given as

The height above the rocks is h=50 m. Let's compute the GPE

It should be expressed in scientific notation

The GPE at the bottom, where h=0

The change of gravitational potential energy is:

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.

explanation:

think its the third option
